Engine-out checkliist

[Packy]

I know this has been asked before but I'm looking for a should-do list of stuff to do on the engine while it is out. Does anyone have a link or a posting for this?

Thanks,

I have my engine out right now. Here's what I'm doing (top of mind):

- Replace CIS vac lines
- check wire ends in engine wire harness and grounds (clean or replace as necessary)
- check for vac leaks (intake runner boots, airbox, etc)
- use Stage8 locking fasteners on the axle when putting back in the car
- classic "triangle of death" oil leaks (thermostat, crankcase breather gasket, oil pressure sensor)
- oil level sender gasket on tank
- oil level sender work?
- fuel injector o-rings and injector sleeves (another vac leak source)
- check the green wire on the dizzy
- new cap, rotor, plug wires if needed
- check for oil leak at the oil cooler (some cars have a weak spot in the case that leaks there. easy fix. Porsche issued a TSB on it.)
- replace oil cooler seals
- adjust valves
- throttle linkage bushings (a lot of people forget this and it will improve throttle response!) get the Weltmeister ones. Pelican sells them.

There is more but I just got called into the doctor for my appointment. More later!

- Good time to check the dizzy
- check clutch, pressure plate, flywheel, TO bearing, etc.
- good time to replace engine sound pad
- how do your motor/transmission mounts look?
- check the transmission shift shaft seal for leaks
- adjust clutch cable
- rear main seal
- check shift coupler bushings
- clean the engine tin and paint it
- any leaks at the oil return tubes?
- clean the 14-pin connector near the fuse panel
- clean the 14-pin connector that goes to the ECU (on the 14-pin connectors you can use a razor blade to spread the pins so they fit tightly - look at the pins straight on and it will be obvious what I mean)
- check and clean the wires at the starter
- clean or replace the transmission ground strap


That's all I can think of at the moment.

How about powder coat engine tin and detail everything?

By the way, you might want to do some research on many of the things I listed. Some simple things like the rear main seal and the oil cooler seals have caused people pain. Make sure you know which ones to buy and which to avoid. If you have any questions about anything on the list do ask. And not everything on the list is a "must-do" -- I was just listing the things I've encountered along the way.
