factory vs. after market replace parts

Featured Replies

Thanks gentlemen,

I have another question. I`m going to have the head gaskets, valve cover,spark plug seals, timing belt and water pump replaced, are there any other gaskets or seals I need to have replaced? And what about the timing belt tenchiner? The clutch/presure plate has 55,000 miles on it, do I replace? Are the after market ones ok to use. The motor has 70,000 miles on it.

And I want to check the compresion does it matter which way I turn the motor? I have it out on a stand.

For sure you want Subaru only for the headgaskets. Leakage on aftermarkets is fairly common.

 

I haven't even really tried after market seals on the newer EJ motors because I've seen enough low quality after market seals on the older one's it's not worth my time. I think you'd be okay most of the time but folks have seen issues with seals too (cam/crank).

 

Clutch pressure plate depends on your driving style I guess and costs. Best to do it while it's all out but if you're easy on clutches and it's got a good bit of life left reusing it should be fine. I would definitely replace the clips, pilot bearing, and throw out bearing.

 

Engine has 70,000 miles but the clutch components have 55,000? I doubt they were replaced at 15,000 so I'm missing something.

 

Reseal the rear separator plate too with the newer metal ones if yours doesn't already have it.

Personally Subaru for HG, crank, cam seals.

 

Subaru or Felpro (usually priced about the same for many gaskets) for intake, exhaust, valve cover. Usually just depends if I'm at the parts store or dealer.

 

Generally the deeper into the engine the more likely Subaru parts.

 

I often do plugs even if not needed while the engine is out.

 

Idlers and WP are up to you. But if you're doing crank/cam seals you'll certainly be in there.

 

I'd use it as a chance to put fresh coolant in as well.

Sorry for the confusion, The other engine i`m putting in has 70,000 miles on it, and my clutch that I have in the car has 55,000 miles on the clutch. They said they had a problem with the clutch padle staying on the floor, and they had the clutch worked on, and thought it corrected it. So are after market clutch kits ok?

Clutch staying on the floor is either an assist spring or the hydarulic clutch itself (don't remeber if there is an assist spring).

 

All seals from subaru. Valve covers can be aftermarket, spark plug bucket seals from subaru.

 

Headgaskets SUBAUR ONLY!

 

Waterpump anywhere.

 

theromstat subaru

 

PCV valve

 

Tming belt any brand name.

Tensioners and idlers yes

 

BTW when you take the engine out the very first thing you do is flush the radiator. Antifreeze and goo can clog a perfectly good radiator when exposed to air.

Good point on the radiator but what is assist spring?

It may not exist. It can be on the clutch fork or the clutch pedal. it is just used to take up slack in the mechanisims.

What engine?

 

An older phase 1 EJ22 it doesn't really matter what brand gaskets you use, they hardly ever fail. A Phase 1 EJ25 you MUST use the latest subaru gaskets or it will fail again. The phase 2 engines I use factory gaskets in as well.

 

Reseal the oil pump and seperator plate, do the cam and crank seals as well.
