Oil Pump, question on pump removal/inspection Options

[dmenche914]

Hello: I have a 914-4 engine out of the car, ready to swap into another car. Engine was a good runner, but, when it got warm, (freeway speed on hot day) the oil pressure got a bit low, not dangerously low, but lower than i like (about 35-40 psi at 3500 rpm as I recall) (my other 914 engine stayed higher at 50-55 psi)

Since the engine is out of the car right now, I'd like to pull the oil pump to inspect it, and replace if its worn.

1. what's the best way to pull the pump without spliting the case? and recommended puller?

2. Might I find oil leaks around the pump after I replace it? (ie is it difficult to reseal the pump once removed?

I ask this, because I recall once someone told me that they are a **itch to remove if you do not split the engine case, and that I would find problems with resealing the pump, unless I split the case to re-install the pump.
Is this a fact?

Anyone have experience with this?


Thanks dave

Hey Dave,

glad to see you back in action, I heard about your work injury.......

I tried to use a slide hammer to remove the pump while the case was still tight and I couldn't get it to budge.
I believe there is a special "bug" tool that will work and is not too expensive.

Got any good running motors? I might be in the market if my rebuild takes too long (IMG:style_emoticons/default/sad.gif)
