Well, for starters, disconnect the battery before doing anything else

Make sure you have a can or two of PB Blaster or a similar type of penetrating oil.

The NA should be pretty straight-forward to pull. Ditto the label / camera / photo comment. I always kick myself after the fact for not taking MORE photos before and during. You can never have too many. With digital cams, it costs you nothing to snap off a hundred pix from every conceivable angle, and store them for future reference. I can't tell you how many times I've used my own photos as reference and wished I had more closeups, different angles, better light, etc. Then again, you can always ask Smoothie for access to his picture album

As for rookie mistakes...hmmm...don't be in a hurry. Work slowly and methodically. It's not a race, and you have nothing to prove by pulling the motor in 30 minutes flat. If I were in your shoes, I'd be more concerned about getting everything cleanly disconnect and detached. You want to be able to drop it back in with a minimum of your budget going to replace things you broke due to careless removal.

The Haynes manual works fairly well for a US car.

I prefer to lift it out, not to drop it out the bottom.

Soak everything with Liquid Wrench, PB Plaster, etc a day or so before starting the job.

i think we have the euro cars which should be the same.

lots of pics..will do

chain hook on points?

ohh forgot to ask...im unsure the actual state of the engine...When the car was delivered the engine sounded beautiful, as for the internals im not sure about their condition..ie valvae guides seals etc etc.

But me being impulsive i removed the whole interior ignition and all before trying a compression check.. any wasy of gauging the engines condition 1) with it still in the car(igntion dash everything inside has been removed not sure how to crank for a compression test?...2)with engine removed(short of actually pulling the engine apart)

You should be able to hook onto lifting brackets bolted on the intake at its mounting surface.

Remove the engine with the engine wiring harness; one or two multipin connectors at the firewall by the coil.

Remove the engine also with the bellhousing attached - only 4 bolts and easier to get to than leaving it in the car.

Remove or drop the front swaybar for extra forward clearance; likewise remove the rad and fans for room (and helps prevent damage), and the coil.

Don't forget to remove the ground straps at the back of the head! Likewise the heater hoses.

That's all that comes to mind right now...

think three times before doing stuff, be SURE you've removed/loosened everything before you do something.

I don't know what strategy you'll follow, but I haven't touched my gearbox.

I've removed my radiator, crossmember and got the engine out quite easily.

Be sure to have an assistant for the things you need one, like hood removal and navigating the engine whilst hoisting etc.

Try to keep the nuts/bolts together with the pieces they belong to (hence, put the bolts back where you got them and twist the nut on) so you'll be sure what went where...

I didn't do that... and I regret that

If you trace back the wire from the starter motor,(the small one, not the batt feed) there should be a connector located around the brake master cylinder. If you open this up and run a wire from the batt to this wire, the started will run, cranking the motor. However, you really need to warm the motor up before a comp test, so see if ou can run some temp wires to simulate the ignition switch.

Absolutely. In my experience, compression test or leakdown test on a cold motor, or one that hasn't been started within a month or so, will yield inconsistent and unreliable results.

In my book - if someone else (other than me or the factory) put it together, it's not in good condition. That select few might be expanded to include a few certified race shops, if I get a chance to sample their wares.

There's no better time to put new bearings in an engine than when it's out of the car. Likewise, to do a headgasket job and lap in new valves, install new valve stem seals.

So that's what I'd do as a minimum; new rod bearings (and check mains, replace if needed), new rings, and re-lap valves and install new valve stem seals. Then you have a NEW motor. Not someone else's idea of a fresh motor (which may involve nothing more than some quarters in the spray wash and a can of spray paint)!

PS - I'd also put in new seals wherever I can get to; rear main, front crank seal, those would be key. So an all-new engine gasket set - gonna want a new headgasket and oil pan gasket.

What they said!

Ideola's comment about taking your time is so true. I'm not saying this as a guy who's done it successfully (although I pulled/yanked/broke one 931 engine years ago), I'm saying it as someone who has had to eat the cost of my own mistakes and those of someone else rushing the job.

Methodical, take pictures, document it...just put a note pad on the roof and jot stuff down on Post Its or a log book, whatever suits you.

Good luck with it!
