Toyota Engine Problems

[slakker]

Someone please she dsome light on this problem for me. I have lost all faith in the Toyota of mine. I have a 1992 Toyota Paseo, 5sp. The car has 96000 miles on it. I have been through 4 engines in the last 8000 miles. Why, I do not know. The first engine went from a thrown rod bearing. The second put a rod through the block (while on the highway). The 3rd was just junk, and the 4th blew another rod beqring. It seems to me that my oil pressure isnt where it should be. What could cause that other than the oil pump. What were theodds of three engines all having bad oil pumps and failing within 1000 miles. All I know is that this is it, it is very expensive and I cant take it. The mods that I have done are . Custom intake (with cone filter), and exhaust from the headers back. Someone please help me, I cant keep doing this. :ffs:

really? I don't know what to tell you amn, my Paseo's engine is 219,000 miles old, and there's no problem with it...maybe it has something to do with where you're getting these engines?

I know exactly what you are saying. What would have meade the original go at 90000 though. I dont understand. I guess this means that no one else has had or heard of such problems or bad luck. Any more thoughts. Thanks for thinking though

well it does seem like whenever a 5e-fe goes, it winds up being because of a thrown rod. Seems like that only happens from over-compression or damn hard driving, but I could buy something from the oil being at fault. Bad pump, a leak maybe. Or maybe a little bit of a lot of things like that. Then there goes the origional, and you buy another from this place that bought a crap engine, and only thinks they know how to fix it. They put it together not quite right, and it goes to hell. in not too much time. Don't blame it on toyota, I've heared stories of people being fired for putting out like 1,000 or so of the product they're responsible for where a bolt wasn't tightened within like 3/16th of the proper specification or something like that, toyota makes damn good stuff, they demand the best from their employees. It's gotta be where ever you're getting these engines, hard driving, and/or the environment, and the ocassional defect, maybe in the origional and one of the others...

I know of exacly what you are saying. My harsh words come from within the deep dwelling of jelousy. Everyone elses toyota is warhead proof. I cant get a good one. I dont know. Everyone of them blew black smoke , was it because of the exhaust/headers. Were they leaking oil past the rings. This is like 3 engines though he same problems in all three are am azing. Thanks though

wonder if maybe that may have had something to do with that, say the orgional took maybe the head gastket lets say out with it, which usually mean you get oil and smoke and all this crap in your exhaust. now all that stuff is just like plaque to an artery, and it built up, and caused too much back pressure, like the body would have a heart attack, and every engine after that went because of the excessive backpressure. I mean that's totally out of my *****, but it's realistic, something like that may have happened... maybe try cleaning out the exhaust piping, getting a new cat, new exhaust gasket, clean the exhaust manifold, then try an engine from somewhere you havn't tried before, and take it easy on it for a while, use good oil, good gas, maybe check your ECU and make sure none of the circuitry is fried, get all new oil and water pumps, check your radiator, make sure that's still in good working order, change all your filters, and if the next engine goes, push your car off a cliff (there are cliffs in the UK, right? I don't know your terrain, I'm thinking it's all hills, but I don't really know) and throw a taquila sunrise after it, and watch that !Removed! burn, then dance on the ashes . Lol, actually, maybe try this, talk to a JDM importer, get a 4e-fte engine, custom exhaust, all new filters and pumps and everything, and an aluminum radiator, and then you should be all good.

i have seen this before, it was that one of the injectors was over-fuelling. Did you replace the injector rail. I suggest you get a complete front clip and drop the whole lot in rather than just the block, I doubt all 4 of ur engines are duff, their must be something else that is causing you to blow these engines.

Brothaman, Thanks alot for the advice. Ive been to that cliff and was out of Tequila, so after many wakeful nights of crying over my beloved Paseo, I have decided one more go is what my will can withstand. The exhaust idea isnt really all that bad. The fuel idea is even better though. It blew black smoke on shifts, I believe because it was running rich. The only way I know how fix that is replace the 02 sensor, Which I did on all the engines. That would fix the exhaust smoke for a little, Then It woiuld begin again, from what I beleive to be the o2 sensor being covered with the black exhaust soot.

The oil light would come on occasionally, depending on its mood. It would either come on when accelerating or when decellerating. Even though it was full of good oil and there should be nothing restricting it. This is all caused by what I believe to be a oil circulation problem. The fuel rail seems plausible because of it always seeming that Im running rich. But these were three complete enines. Oh well. Anymore advice

Could always go the whole way & wack a 4EFTE in...

Bah. Nice. My car didn't have any problems before today, although it has 140,000 on it :D Ignitor died, but that's not a big deal ;)

Were these rebuilt engines or used? And did the mechanic use your manifolds on each new engine? If so, as has been said, something is causing it to flood. The excess fuel washes past the rings and thins the oil. Thus causing your bearing failures. Has it been on a diagnostic machine yet? No need to guess and swap parts, do what the computer says do.
