Does anyone know how to prime an 85 2.5? The oil pump runs directly off of the camshaft, rather that the distributor. Any help would be greatly appreciated.
Thanks,

There is no real way to properly pre oil a 2.5. The best you can do is assemble the engine using assembly lube (vaseline will work in a pinch) on all mating parts. It is best to use camshaft and lifter assembly lube on the valvetrain whenever possible, if you purchased a performance cam it should have came with a bottle, if not, you can find it at some auto parts stores or order it online, all big names (comp cams etc) have it, it's EXPENSIVE but worth it. Lube the cylinders lightly with fogging oil, a rich oil used to keep engines in long periods of storage from locking up. Fogging oil is easy to find at most auto parts stores, and is normally carried by marine and motorcycle dealers as well. If the heads are off, place each piston at bottom dead center, spray the cylinder with fogging oil and wipe gently with a clean, lint free cotton cloth to coat the entire cylinder wall. If you've already bolted the heads on, you can spray the oil in using the spark plug holes and rotate the engine by hand a few times to coat the cylinders. Doing all this with help lightly lubricate the engine until the oil pump builds pressure.
As an added measure, try this:
Remove the valve cover, all four spark plugs,and the drive belts. Unplug the oil and fuel injector, and crank the engine over for a few minutes until the oil pressure gauge reads something and oil starts to spurt from the pushrods. You engine is now oiling in all areas of the block and heads and is ready to start. Note this procedure is really hard on the starter, so if you bought a replacement it's best to use the old one for this before you return it for a core charge.

I JUST noticed while looking back at this post... there is a typo... ...unplug the oil... should be unplug the COIL. whoops!! :lol:
