Oil leak around distributor after O-ring replacement

22 Nov 2011, 06:56 pm

89 Cressida 7MGE engine. Was puking oil out around the distributor
base. The old O-ring was flattened and brittle. Replaced with a Toyota
OEM O-ring. Still getting leakage.

Any suggestions?

I should add, the leakage is much less but it's still leaking.

Yeah, it ain't the o-ring, it's the distributor. I had the same
problem. Got a used one at a Jy and I was set.

Miss my 7MGE, wish I hadn't have sold it.

It can be easy to pinch that new O-ring sometimes.

Also, could be that you are developing pressure inside the
crankcase. Malfunctioning PCV system, too much blowby,
etc could be a contributing factor.

Alternately, is there excessive play in the distributor shaft? Might be
time to have it rebushed, if you can find someone who still knows how to
do that.

You either damaged the new o-ring, or there is debris in the space where the
seal is supposed to happen.

as others say, the new o-ring might have been pinched and torn. was it
tight going back and did you use the distributor bolts to get it back
into its socket?

check again, and check the mount area. on split facings, you can get
oil seepage along the groove obviously.

if the oil is found to be leaking from the distributor's internal shaft
seal, you'll need to replace that. most distributors are not built to
be consumer repairable so if it's leaking, you're probably best advised
to get a fully reconditioned distributor.

I have only had to do that once in my life, to take some
slack out of a worn distributor bushing. It was, however,
a piece of cake. Now, this was a simple Ford distributor
used in the big block engine, but the process was straight
forward and very easy to do.

last time I tried to get a dist part it was unavailable unless you were a
rebuilder. KB

I dont remember now whether I ordered this bushing from
Ford or got it at a local parts house. Toyota parts might be
a totally different matter. Or, you might be lucky enough to
find a suitable bushing from generic bushing sets.

On some things like alternator parts, etc, I have gone to
local rebuilders and they were happy to supply me with
the "rebuilder only" parts I needed.
