Engine rebuild low compression FXT
 
Bought a 04 Forester for a pretty good price, it has low compression in cylinder 4 so Im guessing it needs a rebuild. If the valves check out and it hasnt destroyed the cylinder walls, would it just need a clean and a re-ring kit? Or will it need a complete rebuild... Or should I just buy another 2.5 engine?

You're in for a rebuild if there is something legitimately wrong with it.

I wouldn't just get another block.... those 04's and 05's have frankenstein blocks like the Baja's. Get it rebuilt.

Congrats on the purchase.

My thoughts where to buy a block, Then with that block, rebuild it myself, then when the time comes, pull my engine, pull the heads, send them to get machined, put those heads on the block I rebuilt, and then put it back in. Basically for time. I dont want to pull the motor, then have to do everything, and if the block needs major work... so yeah.

Lets say it was just the piston/rings in cylinder 4, and block was good. Would it be worth it to pull the engine, new pistons and rings, head gasket, then put it back together and reinstall. I would do it myself, I mean if there is no rod knock, or burn valves or anything else wrong, everything should be good for another good while, correct?

Obviously, if your doing all the work already, full rebuilt would be the best option, but spending 3.5k on stuff that is not necessarily needed...Not all about that, rather spend my savings on school.

You should be good with the pistons and rings, etc...

psinuse 04-25-2013 07:33 PM

WELLLLL, yes and no. If your going to rebuild it, you'd be better off buying a new one rather than spend the money on a simply rebuild. Why do I say this? Cause I speak from experience, it will cost more to rebuild the shortblock than it would if you just bought a new one..

pzr2874 04-26-2013 05:18 AM

If he does all the labor Keith?

psinuse 04-29-2013 03:14 PM

Well keep in mind it's not just the labor. Tools for these builds aren't cheap and to be honest the factory does a really good job on these motors anyway, sans pistons...You could rent the tools, but not sure who rents out micrometers and tools of that nature.

[B]Do you think it will cost more $ to have a shop rebuild an engine to stock specs, than purchasing a shortblock or longblock?[/B] I haven't priced this type of thing out in a long while.

pzr2874 05-22-2013 02:01 PM

IIRC the 2.5l longblock was in the $3500~ range. Call your dealer with the VIN. Not sure on the 2.0l

Yes it will cost more. I could sit here and explain every little detail on how to rebuild one of these motors, but to be honest just take the easy road and buy a new shortblock.

Yeah I wanna say the 2.5 and 2.0 shortblocks are around $2400 or so, the heads are what cost more based on the year and model.

Paul I looked at your pic and thought you had bought a mini van at first...lol
