1999 Porsche Boxster Engine questions......

[Johnny-5]

So I recently purchased a boxster with a blown motor most likely due to the IMS bearing and picked up a used 2.5L engine to throw in. I have no history on this engine other then its been sitting at a automotive class for years as a donation for them to learn more about the flat 6 engine. They no longer needed it and is why they sold it. So my question is what should I do before dropping this motor into the car? Ill probably do a leak down on the cylinders and scope it and see how the cylinder walls are but should I do anything with the timing chains, guides, etc? Or do you think a visual would be efficient enough? IMS is going to be done for sure just want to see what else I should do before dropping this in? Dont want to tear the heads off but that was something thats been crossing my mind if I should. Any feedback would be greatly appreciated.

I didnt realize I posted in the wrong place. Could someone help me move this to the correct forum. Sorry.

You are in the correct forum.

 

Before putting an engine that has been used in class for years, I would be prone to pull it apart to make sure everything is there and no one has dropped a screw or nut into the internals.  An engine that has been dormant that long may also have corrosion built up on the crank journals from sitting.

I was afraid that was the answer I was going to get. Dont think they dropped anything into the engine and all the bolts seem to be on and not seeing anything removing the valve covers or anything but you never know. I dont have the full knowledge on rebuilding from the bottom up and if Im going to be getting down into the journals at that point its better off just getting rebuilt from the ground up. Was trying to keep it minimal if possible but doesnt seem like that may be the case. Any other suggestions other then tearing it completely down? 

 

And thank you for confirming this is the right spot to post JFP

There are just too many things that could be wrong as you really do not know what happened to it during its tenure in the automotive class, or before it even got there, anyone of which could reduce it to a boat anchor in one Hell of a hurry.  Always better safe than sorry.

 

Good luck with your project.
