Right. I've managed to get my 99T into a garage - so now i can begin to undertake rebuild number 2 after which i should end up with a decent engine and gearbox!
I'm posting this thread to try and work out what i should actually do! I dont want to spend huge amounts of money but am happy to spend a bit if it means i can get the saab to work as a reliably daily driver for the next 12 months, and it be fun in the mean time.
What i have to work with is (most of!) 2 roughly 150k mile engines.
The one in there now has a cracked head/head gasket problem and slightly knackered looking pistons. The bores looked okay to my eye with the pistons in. Has W.I and looked like it may have been thrashed somewhat (the gearbox is very noisy and the turbo was turned up over 1 bar)
The other engine blew a head gasket about 5 years ago and then sat in a garage with the engine full of mayonaise. Had an elderly owner who probably drove it carefully. Most recently it has sat outside and has got a bit soggy and hence has rust over the surface of the block and in the top of the bores. The top of the pistons look good.
I'm not an engine expert, but i'm trying to improve. Ive rebuilt a nice simple landrover engine before now but this only invloved new standard components and no machining. It looks like im going to have to have some proper work done on this saab one.
My thoughts so far are:
Head
Use head number 2, and get it professionally checked first!
Is it worth getting it very lightly skimmed to prevent any possible futher problems? (as it was in an engine that lost the head gasket too).
I can also get work done on the head at resonable prices by a mates father-in-law who is an engine rebuilder by trade.
Is it worth getting my head ported and polished while its all apart? Will this get me any noticeable improvements?
Is there anything else i should do to it too while its out? I've seen port matching stuff mentioned elsewhere but dont know anything about it. Is stuff like this worth getting done?
I presume that there are valve stem seals in there somewhere too that i could replace?
Block:
The pistons out of engine 2 look better than my existing ones so i could use them. I can put new piston rings on them before i refit them. Ive done this before.
Which ever block i end up using is going to get a new set of main bearing shells in it. Ive also done this before so its no problem. Are there also other shells or bearings on the jackshaft that I should look at/do too?
I'm not sure which block to use. number 2 would be easier as it already out of the car but it has gone fairly rusty and definately needs skimming.
Is it worth getting it bored out very slightly? - Its done 150k miles and is a bit rusty and manky. If i do get it bored out can i use my existing pistons with bigger rings on? or do you need to replace all the pistons too (which sounds expensive and id rather avoid!)
Ive never had any work like this done before, so dont know what to expect!
I have ordered a water pump tool so that i can pull the pumps out and examine them, and replace as necessary (im hoping that one looks good!)
What else is there in there that i should be thinking about?
