andy give me a ring on 07935033535 i need the reg number the engine number doesn't work mate.


i'll try get these as cheap as possible, hopefully the crank will be fine but you will have to inspect it around the worn bearing for damage it may need regrinding? but thats usually when they have ran dry so you should be fine


think your self luck i started the valve stem seals on the gto today and its a bummer of a job!

Andy mate - if you need to ask that question maybe this is a job for SPC(?) I'd be worried you might do more harm than good

i'm sure he will be fine, besides i can always pop down there and lend a hand if he gets stuck on anything

I'd suggest sourcing the full Porsche workshop manual, do a google on Cannell & do a download from there.
I'd strip head off & you have to drop the crossmember (I think) to get the sump off.
Personally I'd take the engine out, the chances are that the crank will need a polish & the Con-rods recircled if the bearings been gone for any length of time. The oil pump may not be too healthy either. That's why I'd have a word with EMC before you start.

Hi all,
Had a chat with Dave(colt 45) yesterday (top bloke, cheers mate) and its given me a bit more confidence to tackle this job. Apparently, its possible to do with the engine installed, but I think I'll take it out to be sure I do it properly. Especially if I have to do the balance shaft as well, plus also any other seals that might be weaping.
I asked the question about taking the head off because in the manual it says on this procedure that it assumes you have taken off (amongst other things) the head. I couldn't see why, I can see now that it shouldn't be necessary, as this would add unnecessary expense/complication.
Thanks Jim, I'll look up Cannell for the workshop manual.
Once I get started I'll do a write up and let you know of my sucess/failure*

*Delete as appropiate

just on the wait now for the prices, goto ring him in a hour.

i'm sure it will be a success and no failure

Andy

I'm sure you'll tackle it with aplomb.

Wrt the head though - even if it's possible to do it without removal (which surprises me but there you go), why don't you look at it as an opportunity here and now to recondition valve gear etc, and get new seals and gaskets on. It might just help regain some of that HP yours has lost over the years?

Adam

i would 2nd that!
headset from berlyn is £96 which is £30 cheaper than euro. sump set wont be much and its easier to do it all at once, maybe re ring it but i heard its best to reline it too which is major money.

Exactly. Best doing it all at once to save future work.

Andy I think you should do what my old man did when he rebuilt his 944 engine - drop another one in it's place temporarily as they are (relatively) as cheap as chips! That way your car does not have to come off the road in the meantime.

big end bearings are £55 a set, main bearings are not available or he can't source any, and piston rings are £80 a set.

I aint a clue how these prices compare to other outlets but they seem cheap enough

just looked on berlyn site and they are just £2 dearer than my supplier for std big ends, i have informed andy not to order anything untill the engine is stripped. there is 2 reasons.....

1, the crank may have been previously ground
2,the crank may need regrinding

if this is the case he would be stuck with a set of big ends that fit anything but he's car.

Don't forget members get 10% from Bert on some items (& if you haggle!)
That's why I said speak to EMC not all 944 cranks are meant to be ground according to the manual.

I've been looking around at prices and it seems likely I'll probably get most of the parts from the states. For a start you can't get balance shaft bearings in this country, so if I'm going to pay the postage I may as well get the other bits there as well. Plus there also alot cheaper you substitute a £ for a $. Just a bit worried the gaskets will survive the trip without getting crushed or bent.
I'll make a decision on how far to go once its apart.
I'd like to get the torque tube reconditioned while the engine is out, has anyone had this done? Any idea of cost?

Andy

I discussed the torque tube with t'other Andy at SPC at the rolling road day and he was telling me they last forever. Is yours noisey then?

Adam

When I had it apart last time, although it turned freely enough, it seemed a bit notchy. As I'm getting some noise from underneath I thought it could be this. It could of course be the gearbox although that felt pretty good.
Mind you its all academic as I'd forgotten I'd have to either take the gearbox out again or drop the rear axle to get the TT out. As I've spent more time under it than in it you'd thought I would have remembered that. So I'll put this on the back burner for now.
