Caterpillar 3208 Solutions This sub-forum is hosted by Mike Hohnstein who has been at this kind of thing for 50+ years now, guess I'm addicted. The saga has been all about progressively larger shop space since then. Honestly, never wanted to get into the CAT 3208's that were originally considered to be a throwaway engine but that's all that works in a FC in my world. Same thing with my Ford toter, that came with a NA, too much effort to hang in a 6, so been at it with the CAT V-8 for 20 years now. In reality you can get excellent life out of a CAT 3208 if it's built correctly. Post your questions about the CAT 3208 engines here and Mike will try to help you out.

Gut feeling is I have the same problem as what John McGinnis had. It sure looks like it anyway. After stopped it will leave about 10 drops of oil on the floor.

How much was the total bill to get those gaskets fixed?

It also feel like my 3208 might be worth this repair even at 4100 hours.

I dropped my bird off at a highly-respected diesel shop here in Winnipeg. They determined the oil leak was coming from the rear seal. The work order says:

diag and check for oil leak-customer says he has oil pressure at 120 psi-would also like fuel filters changed *NOTE: master switch is by drivers right knee


Correction:Pressure wash engine, Run engine to temp, found oil pan bolts leaking at the rear of the pan. Power steering pump at front of engine leaking what looks like engine oil. Down draft tube is making a lot of mess on the transmission, couldn't see any transmission leaks at this time.When the engine was running there was no oil coming out of the flywheel housing but once shut down for a few minutes oil started to drip out from the flywheel housing. needs oil pan gasket, rear seal.Install mechanical gauge, run engine and compare to dash gauge. Dash gauge read 40PSI idle and 120PSI at 1500RPM.Mechanical gauge read 40 PSI idle and 60PSI at 1500RPM.needs oil pressure sender and then retest.
_________

After they examined and determined the front axle had to be dropped, they told me they didn't have the right equipment to do the surgery. They sent me to a local bus company that has more equipment to do this job.

Any comments on the diagnosis, particularly the down draft part?

Did this project on our 82, rear main seal, while working on transmission. Didn't drop the axle. Just slid the transmission back far enough to get access to front seal on the transmission. Used a rolling truck transmission jack. Call if you need too. 580-436-7873

Thanks John. I have the ZF and it's bigger than the MT643, so dropping the front axle is required from what others are saying. This is what makes the job less appealing for most shops. Mike has said 16 hours minimum... so maybe 20 hours for a first time shop... maybe another 6 hours for other issues.

I'm going to see about taking my ZF to the Gear Center... seems like Canada's only heavy duty ZF shop. Good to get those seals changed while it's out. Also going to get the exhaust pipe changed that goes past the front air bag and get new insulation.

I miss some things about the older FC's....
