ummm yeah my 1988 mr2 broke down last night and it wont hold oil pressure when it starts you might be able to get it to move maybe 150 feet before you have no gas response. the crank squels and runs very very rough and leaks a **** load of oil...would this be the ehad gasket or something more major?

Something more major.

My money is on a hole in the side of the block or pan with a connecting rod no longer connected to the crankshaft.

You will have to get it up on blocks and climb under it to look everything over.

Should be easy to find if it's leaking that much oil.

Good luck, keep us informed.

its not that hard to replace the pan is it? i mean if i have a hole in the block then its getting parted out. but if it just threw a rod threw the pan then its going to be a halfway easy fix. i hope.

Throwing a rod is not going to be an easy fix because it means pulling everything apart to fix it and the crank may already be toast. Also bent valves are a possibility as the piston does funny things when it is remote from the rod.

On the lighter side you could just remove whats left of the rod weld up the oil holes in the crank and grind the lobes off the cam on that cylinder to get a 3 cylinder that vibrates to hell

Your motor is almost certainly toast.

If I were in your shoes, I'd give used motors from Japan serious consideration. They are generally lower mileage, and cost much less that having a machine shop rebuild your old motor. Another consideration is that rebuilt engines from machines shops are very short-lived in general.

Before you decide your motor is toast, check the oil lines. There are some pipes external to the engine, around near the oil filter housing. If those break, you'll run out of oil in a hurry--and running out of oil will make your main bearings scream. Hopefully you haven't screwed up your crank and bearings by running without oil, though that's a very real possibility.

you're saying that its better to just gamble on a used engine vs having the one you own rebuilt? is that just in this case or in all cases?i have an engine with 200k miles on it and i was trying to figure out which route would be better. the engine seems to run great right now and i was wondering if it would be better to strip it to the block and rebuild it or to buy a used one from japan. i am thinkin the rebuild would cost more but would it be worth it?
