danzick Posted October 27, 2011 Share Posted October 27, 2011 so when you start it when its cold, there is this nasty loud rattle that comes from the engine. eventually, the rattle goes away when the car warms up. well i was driving it home on the interstate tonight, and the rattle started doing it really really bad and extremely loud at rpms over 3000. what is this? its not really a knock, its a rattle like the exhaust pipe is loose or something but its coming from the motor.

bheinen74 Posted October 27, 2011 Share Posted October 27, 2011 what transmission do you have, auto or 5spd? if auto, could be cracked flexplate. Could be heat shield rattle or and exhaust bracket. could be a timing bearing component going bad could be waterpump could be power steering pump. etc. Quote Link to comment Share on other sites More sharing options...
Subruise Posted October 27, 2011 Share Posted October 27, 2011 pinging? what kind of gas are you using? Quote Link to comment Share on other sites More sharing options...
idosubaru Posted October 27, 2011 Share Posted October 27, 2011 there's a lot of different possibilities, need to narrow it down more. if it's doing it at first start up, that makes it really really easy to track down, just open the hood or crawl under it while it's making the noise. heat shields are a really good possibility. start there and inform us as you rule those out. front or rear of engine, left or right?

Loyale 2.7 Turbo Posted October 27, 2011 Share Posted October 27, 2011 (edited) Key Words: ... eventually, the rattle goes away when the car warms up... That sounds to me as the "Tick of Death" sound like if your engine has a very Low Oil Pressure and / or is using a Monograde or thick oil. Could you let us know which kind of Oil is your Subie's engine Using? Maybe is time for a Engine internals cleanup. Kind Regards.

danzick Posted October 27, 2011 Author Share Posted October 27, 2011 motors been rebuilt about 15 thousand ago(supposedly) and they must not have got the bolts tight enough. Quote Link to comment Share on other sites More sharing options...
Quidam Posted October 28, 2011 Share Posted October 28, 2011 So, do you have a replacement flex plate on hand? Don't know where you are but I could ship you one out in the a.m. Doug lmk Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted October 28, 2011 Share Posted October 28, 2011 What engine? There were some issues with flex-plate cracking in some of the EJ engines - I'm assuming EA since you are in the EA forum but figured you ought to clarify. Also important if you are running a FT4WD tranny as that's going to likely be different. GD Quote Link to comment Share on other sites More sharing options...
danzick Posted October 28, 2011 Author Share Posted October 28, 2011 its an 88 SPFI 1.8L ea2. yes, 4wd wouldn't own it if it wasn't! thanks for the offer Quidam, there is a guy in my area who loves working on these old Subaru's, and the mechanic said he might have one laying around. i will keep your offer in mind if i do need one.
