Do you have to know what size washers you need and if so what did you order for the 3/8 ARP bolts 2Munkys ?
I wouldn't mind ordering some of these today if I get the chance so I can get the manifold off and replace the gasket at the weekend. I bet its the nearside again
NL3/8"ss. 10.3mm ID, 16.6mm OD, 2.2mm thick. I'll double check 'em when they arrive.I wouldn't mind ordering some of these today if I get the chance so I can get the manifold off and replace the gasket at the weekend. I bet its the nearside again
The stainless are double the cost of the standard washer; that's probably what you have Fat Griff.
Ian, you need to e.mail your requirements and address so they can reply with an invoice: enquiries@nord-lock.co.uk . Small bags of 10 are available, other than that the denomination is 100.
I too have another gasket blowing; hoping to fix it all for good with the ARP bolts, Nord-locks and Clever Trevor gaskets.
If you're sliding one gasket in I'd say it may be possible but you'll probably have to loosen all of the manifold bolts on both sides to get enough freedom of movement to do the job. Possibly support he weight of the down pipe on a trolley jack as well?
Last time I had the big joint apart I used firegum, worked fine

Can I just confirm that the S/S nordlocks work ok with S/S bolts? ie the teeth on the outside of the nordlocks are able to bite and grip the bolt head enabling the special ramps to function.
Basically I bought zinc nordlocks which work fine on steel bolts but are unable to bite into my S/S ones so the whole system fails as it slips like a normal washer.

no I definitely have nordlocks, just the softer zinc ones so they are unable to grip the harder stainless steel. The fiction between the bolt head and the nordlock is therefore less than the force needed for it slide on the ramps when undoing, so it acts like a normal washer and slips. They work as expected on the original soft steel bolts as the teeth can bite into the metal and then the only bit that moves is the ramps.

My pre-cat has the exhaust bolted to the bellhousing. don't the other cars have this?
Mine (a 500) has the exhaust bolted to the side of the sump or block somewhere on the LHS just rearward of the the clamp down there - I assume that's standard and helps take the weight.Ruari
