EA82T Oil leaks

[2K4 STI]

This is spawned from Huck369's thread about the EA81 oil leaks.My 87 EA82T leaks from what looks to be the front of the motor.

What are the seals that should be replaced on the front of the motor?Im planning on doing the oil pan at the same time but dont know what seals lurk behind the timing covers.

Oil pump seals, cam seals, and front main seal.

what he said - the EA82T has three oil pump related resealing parts:

pump to block "mickey mouse" gasket

oil pump shaft seal (behind the sprocket)

an o-ring

 

behind the cam caps (that hold the cam seals) also lies an oring, you'll need two (one for each side). buy a cam seal "KIT", not just a cam seal. they will come with one seal and one oring for each side. do not just replace the seal.

 

keep in mind the oil pan gasket is a serious PITA to replace, particularly for the first time and for those that have never seen an EA82 torn down before, the baffles and oil sump are hard to get to clear, requires jacking the engine up, removing motor mount bolts, and often even removing rear trans mount bolts to tilt the entire contraption "back".

 

i'd replace all the front engine oil seals/o-rings first before the oil pan. see if maybe that's enough to cool down the oil leaks for you. replace as many hoses as you can too...turbo hoses are a good place to start.

Thanks guys.

Ive torn down and rebuilt the engine in my old 04 WRX before so hopefully doing the front seals on this engine wont be so bad.
