Can Head Gasket Problem Happen Again Subaru

What is a Head Gasket? What Does it Exercise?

Do you hear the term "head gasket" mentioned, but not sure quite what it is? And then many times you'll hear it referred to in relation to a vehicle's engine, so that may lead to some confusion as well for those who may not be equally familiar with the inner workings of a vehicle as others. Hopefully, this skinnied downwardly explanation will aid.

While the head gasket is unlike from the engine, they are related, in that the engine relies on the head gasket to proceed it running. Most engines are fabricated upwards of two components, the engine cake and the cylinder caput. These 2 parts must seal to one another in club to work as 1 piece, otherwise the engine volition fail. If you think about the sealing function that must occur, that is facilitated by the head gasket. The head gasket is the sealing layer that is sandwiched between the cylinder head and the engine block. When the caput gasket is properly tightened, the cylinder head will vanquish the head gasket into the cylinder block, causing whatsoever imperfections to be sealed by strength.

Just as the engine is needed to keep a vehicle running, the caput gasket is needed to continue the engine working.

Subaru Caput Gasket Issues

Subaru vehicles have experienced head gasket bug and you lot hear about it oftentimes enough that anyone shopping for a Subaru is surely to stumble upon information pertaining to Subaru'southward faulty head gaskets.

While it is true, there accept been head gasket failures on many Subarus, it is important to notation that the bug practice non apply to ALL Subaru models. Unfortunately the Subaru head gasket problem has received and then much attention on the web that many consumers may think it is all Subaru models that are afflicted and that merely isn't true. There is also a misconception that it was the same head gasket issue affecting all models. Again, this is non true either.In that location are two carve up groups of years where head gasket failures affected a few models and the problems associated with each grouping are unlike. Both involve leaking, but i is an internal leak and the other is an external leak.

Subaru Caput Gasket Problem Years – First Round

The start grouping is specific to the 1st gen EJ25D ii.five liter engine found mainly in the Legacy, Legacy Outback, Forester and the Impreza from 1996 to 1999. These engines suffered from internal head gasket leaks. The primary reason they experienced issues is because the engine overheated as a upshot of losing coolant due to the head gasket leak. This leaking coolant resulted in the coolant system not properly working. If the cooling organization is not properly working it can't properly regulate the amount of estrus in the engine, which will then lead to an overheated engine. Some of the symptoms seen with this leak are an oily residue establish in the coolant overflow canteen and a possible exhaust, fuel or sulphur smell in the overflow coolant bottle. Some other symptoms are higher than normal coolant temperature gauge readings, and intermittent overheating during long trips. In some severe cases you may fifty-fifty experience a cracked radiator. Below are the models that were outfitted with the EJ25D 2.five engine and may likely experience this head gasket leak.

• Legacy LSi, GT and Outback 1996 – 1999
• Impreza 1998
• Forester 1998

Subaru Caput Gasket Problem Years – Second Circular

The 2nd group of caput gasket issues came with the EJ251, EJ252 and EJ253 two.five liter engines. These head gaskets suffered from external leaks betwixt the cylinder heads and the engine cake causing coolant and/or oil to leak out between the head and the block. This head gasket failure does not typically cause the engine to overheat. Withal, because of the way the engine and coolant system are situated there could be issues with coolant mixing with the oil. When coolant gets mixed with your oil, it dilutes the oil and hinders the lubrication, making it easier to tear upwardly some other parts like a rod bearing or possibly crusade your engine to seize your engine. While these are astringent instances, information technology is possible, then getting that head gasket leak addressed should not be put off. Models afflicted were those with these specific engines and include model:

• Impreza 1998 – 2003
• Forester 1999 – 2004
• Legacy 1999 – 2004
• Outback 2000 – 2004
• Baja 2003 – 2005

The Subaru Caput Gasket Fix and Why the Caput Gaskets are Declining

While it makes reasonable sense to point the finger at the engine, specifically the boxer engines, at that place is research that shows that the bug stem purely from a faulty head gasket. The manner the head gasket was made is the root cause of the leaking issues. Subaru had been using a multi layer steel head gasket (MLS head gasket) in the by, and when these engines were introduced into these models mentioned above, they switched the actual head gasket to one that is a single layer gasket with a graphite blanket. This graphite blanket has been known to chip, strip and peel off at around 100k miles. When the coating strips off, information technology is no longer able to seal appropriately, hence resulting in a leak. Coolant is going to leak, oil is going to leak, and sometimes both will leak. These graphite coated gaskets are the problem and what has acquired the caput gasket failures.

Nether Subaru'due south bumper-to-bumper warranty, which is 3 years or 36,000 miles, a faulty caput gasket is covered. But these head gaskets are known to last virtually 100,000 miles, which is well beyond the 36,000 mark. And according to the data and possessor experience testimonies, these caput gasket problems generally occurred anywhere betwixt 120k and 150k miles.

Subaru is aware of the head gasket issues and in 2022 began outfitting all their models with different head gaskets that have rectified the upshot.

Pro-Tip: Before your manufacturing plant warranty expires, information technology's a good idea to have your Subaru completely checked out to ensure everything is working the way it should. If an result is discovered, you can have it resolved prior to the OEM expiration date while you lot're still covered.

If y'all own an older Subaru or considering an older Subaru, we recommend investing in an extended warranty to give yous peace of heed in the event of an unfortunate breakdown or repair is needed. Extended warranties for older and used Subaru vehicles are available at https://olive.com/.

Toll to Prepare a Subaru Head Gasket

As you would expect, fixing a diddled caput gasket is quite expensive because the labor required is intensive requiring the engine and cylinder blocks to exist pulled apart to get to the gasket. The average cost to supplant a head gasket is virtually $1,000, just can range anywhere from $1,200 to $one,400.

If you lot opt to DIY, it is recommended that y'all use a Subaru MLS gasket, otherwise known equally a multi layer steel gasket. These MLS gaskets do not have a coating on them – no coating, no leaks.

An aftermarket head gasket is not recommended. We understand that some may be weary of purchasing a head gasket from Subaru, since the head gasket bug are associated with Subaru, but information technology is important to understand that the head gasket failures are acquired by the type of head gasket that was used, not the actual engine or fifty-fifty Subaru's craftsmanship. The type that was used in the models that had bug were unmarried layer graphite coated head gaskets. The ones that are recommended are multi layer steel head gaskets (not coated).

Regardless of whether you make up one's mind to tackle the fix yourself or have it to the dealer, yous'll desire to asking that a MLS head gasket is used. As of 2014, MLS head gaskets are beingness used, but information technology doesn't hurt to double cheque.

Pro Tip: The head gasket model number for the faulty head gasket is 11044A6433 and should exist avoided.

Exhaust Smoke – White smoke or sweetness smelling smoke coming from your exhaust means that your coolant is leaking into the cylinders and being turned into steam while your engine is working.

Reduced Engine Power – The head gasket seals in the pressure used for combustion in the engine, so when a head gasket is croaky, the engine will lose power.

Visible Leaks – Leaks outside of the engine of coolant and/or oil is another telltale sign of a head gasket issue. If the engine or coolant gets too depression, it can crusade serious damage to the engine.

Using antifreeze is besides recommended by Subaru, besides as a coolant additive for Subarus with the second gen engines. Make certain your mechanic inspects the coolant lines, checks the color of your fluid, and of course, that the coolant is topped off.

Modify your engine oil on a regular footing – Our cars do not combust 100% of the oil, so any oil that is left over (unburnt) can go into the crankcase where information technology may mix with the engine oil. The longer this oil is left in the engine, the more diluted information technology volition become and eventually eat away at the seals and gaskets.

Take care of your battery – Make sure your battery is clean and inverse out regularly. If yous notice whatsoever corrosion on the actual batteries, your battery needs to be cleaned. Batteries are meant to last 3 to 5 years, afterwards that they can vent out large amounts of acrid.

Avert not-OE parts – Factory parts are used specifically to maximize your vehicle'southward life and functioning. Saving dollars on non-OE parts and fluids may cost you more money in the long run. For instance not-OE spark plugs can cause either too hot or too cool combustion temps, which volition result in how much your heads and gaskets expand.

Know your Warranty Timeframe – If your Subaru is still under warranty make sure to have it fully checked out by a certified Subaru specialist earlier the warranty expires to make sure there isn't an issue that could be covered by the warranty.
