Hi,

Back here again after not needing help for more than a year.

My daughter thinks she's lost a timing belt on her '87 GL D/R. She claims she got it home on 2 cylinders.

Searching through posts on timing belt replacement, I see that the 2.5 is an interference engine, but I didn't find anything out about the 1.8.

If there's internal damage it goes to the wrecker, it's too tired anyway.

Thanks,

Ray Mac

all the ea motor were a non interference motor

nope. non-interference. put a new belt on and you're done. if a timing pulley bearing seized and heated/busted the belt you'll need to replace that too. the 2.5 EJ25 motor is new...didn't come out until 1996. any Subaru 1995 or earlier is non-interference. after that it's a mix, depends on engine.

OK, thanks, that gives me hope.

I am also glad that during my search I found out about the other things that should be taken care of along with replacing the belt.

Technically the ea81 and all the pushrod engines are interference its just next to impossible to have anything collide internally.

Yep - and if they did collide, it would probably just bend a push-rod..... but then *if* they collided that would mean something else (timing gears) is totally borked. That's why the later EA82 pistons have the valve cut-outs in them. Which would make it a no-no to use the RAM performance pistons in the EA82 and ER27 I would think..... at least not without a regular maintenance routine for the belts.

i believe they can manipulate them to retain the non-interference design if you want. been awhile since i talked to them, but pretty sure they are flexible and there are options.
