I have a 1994 GMC Jimmy 4x4 with the 4.3L "W" engine. Son came home today
and the thing is pouring oil on the ground. Appears to be coming from the
area behind and inboard of the left exhaust manifold collector. Seems to be
where the oil filter ought to be but I have the remote filter.
Is this the connection point for the remote filter? If so, is it known to
leak? Easy repair? Are parts (gaskets or ???) available?
Comments and help would be appreciated.
Probably the oil cooler bypass hoses from the oil filter adapter on the
block to the remote filter, very common, not easy access without a lift, and
a very long extension working from the front. Any parts store can supply the
hoses. Or NAPA can make them if the custom make hydraulic lines.
Just had my 94 done by indy shop. GM hose and seals = $92, Labor
1.4hrs x$85, total = $218
I had done the "remote filter to radiator cooler" hoses myself,
but when "block to filter" hoses started leaking, one look at
labor involved convinced me to have someone else do it.
I think you are right. I started to take it apart -- starting with the
engine to bell housing brace. Got it off but didn't have the right
equipment to proceed so I reassembled. It took me and my 20 YO son almost 2
hours to get the block bolt for the brace reinstalled.
I just added 4 qts of oil and will have it towed to a shop. Hopefully, I
can get the deal you got.
Thanks for the info.
Well, I got my truck back today. Fortunately, they fixed the problem.
Unfortunately, it cost more that Reed paid -- mine was about $450 (I live in
Southern California, but they don't take "sunshine dollars" in payment).
Turns out that the adapter plate (not the hoses) was leaking. The O-ring
had split but the adapter plate also had a crack in it. Shop replaced both
and it seems to be holding.
They added a dye to leak test -- will go back next week to be sure. Looks
good so far.
Thanks for your input.
