Could be the oil pressure sensing switch starting to go bad. Oldmics

Oil Pressure - Seems High To Me
Oldmics replied to Oldmics's topic in Old Gen.: 80's GL/DL/XT/Loyales...
The real gauge says 20 at idle and its still up around 60 when at hiway speeds. I"m O.K. with those readings. The original dash gauge would only show 80 pounds all the time and would not register the 20 at idle. I"m not gonna worry about the dash gauge and will just rely on the newly installed real gauge. I am aware of the Rotella oil being compounded for diesel applications.I purchase it by the drum for my trucks and antique cars since it has a high quanity of ZDDP for solid lifter machines.

1990 EA 82 EFI engine I was concerned that the idiot gauge in the dash cluster was twisted up so I installed a real gauge. Reads 67 lbs cold. Have not run it up to temperature since I put the gauge in so I dont have a warm pressure reading. I use Shell Rotella oil 15-40 . Oil pressure seems pretty high to me.What would cause such a high pressure? What do you guys think? Oldmics

Its a 1990 EA82 automatic trans, EFI engine. Did some searching and I believe its supposed to be 20* BTDC. Now I assume its hook the timing lite to #1 and view the timing marks on the flywheel and adjust the dizzy as necessary Heres my real concern. It appears that the dizzy is already twisted to its clockwise maximum position. So if I need to rotate it more in that direction should I pull the dizzy and drop it back a tooth (assuming it has a gear- Amenrican engines that I am familiar with have a gear) I wanted to add a few degrees for some more pep in this dead rump roast engine. Am I on the right track? Thanks for any replys,Oldmics

Thanks for all the replys.The kicker is that I had recently changed the oil and filter.It had not been run 1000 miles since the oil change.So I question that it was low on oil as it does not leak. I did notice and hear some additional valve clatter just before the engine quit.Thats why I was sorta believeing the mechanic about it being low on oil-but just not 100% sure. I have had the car repaired but still need to monitor the oil pressure with a real gauge on it.The mechanics comment about the seized cam could possibly have been the tensioner seized. I will report back in a few days. Oldmics

Not sure how it happened but my 1990 Sub wagon (2 wheel drive automatic) ran low enough on oil to seize and snap one of the timing belts. The mechanic that worked on it said that although it was seized on the broken belt side he freed it up and replaced both belts. My question is how bad has this damaged my engine? Its an original mileage 58K - EA82 engine.The mechanic said get rid of it.But he also said that those engines were only good for about 80K and then they were worn out. The wagon is pristeen with no rust at all.I"m considering rebuilding the engine.Perhaps running the current engine till it dies and acquiring a junk yard rebuildable core. I realise there are no gaurantees but opinions are welcomed. Thanks,Oldmics

O.K.-Put in the new O.E.M. thermostat and the temp gauge now reads a bit higher. The heater really cranks now so I am happy with those results. Still have the oil pressure gauge going all the way up as soon as I turn the key to the "on" position. I dissconnected the oil pressure sending wire and as soon as I turn the key on it goes to the max position without the engine being started. So is this a short in the wiring harness? Possibly in the dash cluster? If its in the dash cluster I can also dig into the sticking tachometer issue. Can someone explain the tach operation and wiring to accomplish the tachometer feature.Its obviously an electrical interface of some sort. Thanks for any assistance. Oldmics

If you have them all-lets do it.
How do you want to be paid.I would think you need a few bucks for shipping also?
