OUCH, melted pistons too. Actually from the initial pic of the block I was going to say it looked like the HG was dropping water into 1,2 & maybe 3 from the colours but now I see the melting it's probably just cooked white through running way lean/hot &/or pre-ignition (pinging I think it's known as in the U.S?)

Definitely a full stripdown job here, you'll be lucky if the bores aren't damaged from the meltdown & if it's got really hot the head & block may be warped.

I can't remember now, was the car running when you bought it/until you stripped it? Must have been screaming for mercy for a while... Sorry to see it's that nasty & damn I hope there's nothing like that waiting in my motor!

EDIT-: OK I've reviewed the post & it WAS running when you bought it. How oh how was this thing not clacking & banging & rattling to high hell, not to mention running on 3 or 4? Best of luck with the rebuild, I think if I found that I'd just find another engine...

yea strangly there was no noise or anything that made me curious aout the reliability of the car. and yea it ran fine for only having 4 pistons running. lol in fast i thought it was pretty fast too... i wonder if im gonna feel alot more power ofter this rebuild.

well the damage isnt bad at all and the rebuild kit that im getting has pistons included so it shouldnt be bad at all. overall costs of the shop are 565!!.

sweeeeeet.

so yea ill put some pics up soon. were about to get the hoist to lift this bad boy out. good thing i got temporarily laid off......

Good god.... if that sad engine left you feeling that the 3500lbs slab it was dragging around was fast... you might want to reconsider the rebuild and just swap in a nice rebuilt 4 cylinder from a Celica or something... I don't know if you'll be able to cope with much more.

No sounds... could be because it had finally finished coughing up chunks of lung and moved on the whole dying quietly stage. That thing was hurting... I'll be amazed if a complete rebuild isn't required (including boring the cylinders and polishing the crank).

You already got the quote? $565 for what?

cvbikeguy · 12-01-2009, 07:49 AM

Hahaha yea I might as well. I can't wait to drive it once its done.

The quote was for the valves, polish, shaving the head, and bored

And you're doing all the assembly and disassembly I presume? If you're going to a metal head gasket find out what the finest RA they can produce is. Also make sure they machine the block WITH the rear timing belt plate in place!

Yes I'm doing everything myself. I shouldn't have to go to a MHG unless I'm hoping to get 600+ HP out of this right? Am I fine just getting the factory? And yes I will definatly have the plate on if the machine it. Already read Ihatehacks rebuild thread

and did you see my link on that rebuild kit on ebay? Looks good right? Thanks for your input cre. Your a lifesaver
