I have been trying to resurrect an '83 GSL that the previous owner stated was in storage for an unknown number of years then driven some for a summer till the cat. converter fell off. Odometer reads 129k. 3 of the 4 calipers were seized so i doubt it was driven very far.

In the process of replacing parts and testing the mechanicals I have found out that the Metering Oil Pump is dead. I have no clue as to how long its been nonfunctional. I highly doubt the previous owner premixed.

The question is : Is there a way to reverse any damage that might have been caused by a non-functional mop?

Gas in the tank now is premixed at a rate of 1oz per gallon.

TIA, Norm

 

I know you probably don't want to hear this, but the sad truth is "NO!" If the OMP has not been functioning, then there is obviously going to be a good amount of wear and tear there depending on how long the problem was let go. Extra friction in the engine will result due to a lack of lubrication, and engine components are going to wear faster than normal. The only thing you can do once your internal engine components have been damaged is to replace them. There is no magic fix, or secret chemical to dump in.

 

My 120k old engine from my SA had some seriously ugly housings. I drove it for 2k with no OMP before I realized it wasn't working, GOK how long the PO was driving it like that.

The engine made 75psi compression when I pulled it out of that car. Now, peripheral ported but using ALL (repeat *ALL*) of the old internals and seals, it makes *90* psi compression. How does compression get 20% better despite closing the intake port way later? I dunno but I ain't complaining
