My son has an 88 Toyota Pickup. 4x4, 22R-E engine, and it leaks oil like a
sive. I look under the car after he has driven it for a while, and it lookas
as though an oil bomb has exploded under it. I know something needs to be
fixed, but I am having a VERY hard time locating the leak. It seems to be
really bad on the passengers side of the car (oil all the way under the
fender wells). But the oil seems to get everywhere underneath.

I was wondering if anyone had a suggestion as to the most likely place those
engines leaked, and any suggestions on methods to find it. Any and all
pointers/suggestions are appreciated.

Thanks,

Phil

There is a known problem with the 22R-E engine of that vintage that
eventually (100,000 miles or more) something in the valve timing chain
assembly (don't remember off hand what it is) will wear out causing the
timing chain to rub on the inside of the timing chain cover and this will
cause oil to leak as well as wear the timing chain and when that breaks the
engine is toast, or at least needs a complete rebuild because that engine
doesn't have enough clearance between the pistons at TDC and an open valve.
If you can narrow it down to a leak near the timing chain, I would replace
the timing chain, the timing chain cover, all the oil seals there, and
inspect and/or replace the timing sprokets. You might also look into some
of the bearings. It's been a long time since I repaired, then gave away my
'87 to the kid that helped me with it and I don't remember all we did to it,
nor do I have the shop manual for it anymore.

In cases like that you usually need to clean them up or drive them in
some mud puddles to find where the leak is coming from. Once driven in
mud puddles or cleaned up, let it dry, then when you start it, the fresh
oil will show up fast.

Maybe the oil filter is just loose?

It LOOKS to be a front seal. At least that is where I narrowed it down to.
But what youhave siad is worrying me. The engine has 224K on it. I am
planning on pulling the oil pump to replace the front seal. Any thoughs on
how I might diagnose the timing chain issue while I have the oil pump off,
without tearing into the assembly?

As I recall, you can remove the timing chain cover without too much trouble
and inspect the chain, cover, etc. Mine was pretty obvious. If you don't
have a manual I strongly suggest getting an aftermarket one like Chiltons or
Haynes. That will aid trendously in and tear down and rebuild, for
instance, I know we removed the water pump, radiator and a few other parts,
but we did some other repairs as well (it had just rolled 200,000 miles and
I figured it was time for several preventative repairs anyway). When we did
mine, the kid did a some of the work while I was away. That plus the other
repairs and the fact that it was 9 years and 4 cars ago kind of fogs my
memory of the repairs.
