Rod hitting pan

[Don W.]

Just for benefit of whom ever. It's been talked about before, but I had not seen it 'till it was to late.

Anyway, had to support the motor to change the mounts right. Take great care to be sure to use a block of wood (in this case a 4X4 on end to reach the pan from the jack). Even angle the block slightly so it fits square to the bottom front of the pan. You can hear this coming. Everything back together (see my other threads). Fire her up and it sounds like the worst rod knock you ever heard. I know immediately whats wrong. With my friend's help (testing this 50 yr friendship

) we have the dif out and the pan off rather quickly. We're experienced now.

That's my wife's hand. Moral? find some other place to lift.

Oh ya, only ran it for a moment. Pan is going back on tomorrow. It just amazes me to learn the the pan is THAT close to the rods.

Once you get away from the sump its pretty close. I use a block of wood between the jack and the harmonic damper rather than lifting against the pan. Im careful about how much pressure I put against the damper and some ppl may flip their wig over doing that but Ive been doing it for just over 20yrs with no problems yet.

Holy crap...Ive been tinkering with cars for over 20yrs! Im getting old :tdown:

i always jack it that way too, not just on the clone either, in my everyday adventures working on cars

Doing my motor mounts, I put the jack on the inspection cover of the transmission to lift everything up. I was too paranoid of crunching the oil pan to put the jack on there.

Re: Rod knock

oops! I once had customer that was to cheap to have his brakes fixed at our shop so he proceded to do it himself.he jacked the whole truck up by the oil pan crushing it and the oil pump pickup. it did seem to stop well when it was towed in and the guys pushed it into my bay to fix the pan.

Re: Rod hitting pan

Right now I switched to jacking under the cast alum pan under the TC. Works. I changed the title also to more reflect the problem. My main reason for posting was in hopes that someone else doesn't have the same problem. Like I said I could not believe the racket this made.

As always, appreciate everyone's comments. Should have the truck back on the road by this weekend. Looking forward to THAT.:tup:

An Myclone, count your blessings, been tinkering about 49 years.:rotf:

Well it's back together. Geez. For some reason the front dif was being real stubborn this time. Anyway motor runs fine and quiet.
