Is the 1.8 an interference engine?


Recommended Posts

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

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.

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.
