Further to my other thread, Here is a list of my current thinking of what to do to the engine and gearbox for my proposed transplant.
Gearbox first. Really only intending to clean the Transmission fluid filter and refresh the fluid. Will need 2 new gaskets apparently. Not checked availability for these, as yet.
Engine wise only intending to do what I consider the essentials. Engine has around 100K on it and was running fine when removed. However, it has been off the car for around 2 years.
Cambelt and other Aux belts
Oil and filter, obviously.
Probably do water pump and Thermostat, as I have them.
State of Cam cover gaskets are an unknown so I'm going to change them while I have such easy access
Clean breathers and throttle body.
Probably change the rear crank seal while it is all apart.
Am I missing anything obvious? Am I doing anything unnecessary?
Regards,
Graham.

I think that is a pretty reasonable list.
Cleaning the breather box on the back of the block and oil cooler would be two further items, but i think you've pretty much covered everything else ;)
-
Plugs. n/s/r will be much easier with engine not in the car. ;)
Possibly HBV too.
-
I would definitely do the rear crank seal. The front crank seal is probably easier in the car.
With the engine on a stand, and the cam covers/belt off, I would change the camshaft seals too. That's the time to change the thermostat, as it doesn't need to be separated from the transfer tube if the cambelt cover isn't in the way.
Strip and clean the breather box.
Replace the low oil-pressure sender.
Clean the block thoroughly now that you've 'fixed' all the usual oil leaks.
Greasing the aux belt tensioner bearing should be done whenever you have the belt off, but at this point I would spend a tenner on a new one.
If you're going to change the gearbox filter, then pull the torque converter and drain it.

Am I missing anything obvious?
Drop the sump and make sure the oil pickup pipe/strainer are clear. It's only about the size of a 10p piece, and if the gauze gets blocked with silicone sealant or other debris it'll wreck the engine.
-
Yes, all that makes sense. Thanks.

The breather box at the back of the block. Is that the part where some folks have removed the rivetted lid and then re-fasten, so they can get to it later?

You won't need to do it again.
-
What Nick said, but yes, that's it. :y
-
Oh good, that's even easier.
Thanks for confirming.

Plenum gaskets (plus cleaning out the plenum)
Thermostat
Depending on engine, oil cooler (some had stainless steel ones fitted from factory).
-
Plenum o rings and seals are fine to reuse if treated with care :y

I was more thinking, if they are original, they are at least 17 years old and will have been off a few times.
-
I have only replaced them once, and only because I had bought them. The one that came off were kept as still serviceable and ended up being given to another Forum member as spares.
The breather bridge tophat seal is a different matter.
-
To be honest the only time I changed the plenum gaskets was when I got them as part of a gasket kit, so I might as well fit new ones.
-
Talking of gaskets, how to best go about getting some of the ones I need.
I have the Cam covers and some spare (used) Plenum gaskets, but others such as the Sump (are there two?) and the gearbox (to clean the filter) also has a pair apparently. Are these best ordered individually or are their other sets which might be useful?
Having never seen any of these parts apart, it is difficult to see from fuzzy diagrams what is it you need. i wonder if it might be easier to take it apart and then buy the required gaskets. Sounds a bit backwards, but some of these are quite expensive and I don't want to buy a bag of gaskets, many of which i am unlikely to need.
Regards,
Graham.
-
An Elring, or similar, top end gasket kit should have most of it in ;)
-
thanks, I'll have a look and price that up.
