Hi Ken,

I used to always use the loctite stuff supplied by SJ sportscars, its an orange colour, no setting and in ultra thin! What the part or code number is though i cant help you, ring sjs or hopefully somebody will be along shortly with the product code or another product that they have had a good experiance with, having said that sjs use this stuff themselves in the workshop which speaks volumes also i have had no dramas with it!

Regards danny

I know it's a few £s more than SJ, but it's a lot more volume, so if you have more than one vehicle it makes financial sense.

When were the cam housing gaskets deleted? I thought (not based on any evidence!) that the S1 907 would still have the paper gaskets?

they deleted those gaskets back when moby dick was a minnow,,,if that helps,,lol

they deleted those gaskets back when moby dick was a minnow,,,if that helps,,lol

BTW,,if you want oil leaks and big problems when doing a valve adjustment,,then yes use them,,lol,,,,just my 2 cents,,

One caveat on using the loctite 518 and the kleen and prime.

I was doing a shim job this week and used Permatex Surface Prep and Activator for anaerobic sealants with the 518 and it caused my valve clearances to open up .002-.003 using the sealant over the dry fit measurements. I actually did it twice before I was able to determine that the activator was causing the problem. It was causing the sealant to cure much faster and increasing the sealant thickness way over the .0005 specified before I could get it torqued down.

When I sealed the tower the third time without using the surface prep/activator the clearances were fine.

I don't know if the loctite kleen and prime is an activator as well but if it is, it may cause a clearance problem.

Thanks for the info Ralph, that looks like it could be a better alternative than the 518. Have you used it yet and been able to determine if it's an improvement for sealing the cam towers?

I don't think any Esprits had gaskets when new; they are all, AFAIK, just sealer + the O-ring around the oil feed.

I doubt the paper gaskets lasted past 1974-75. Quick way to tell: if your oil feed hole has no provision for an O-ring, then it probably originally had a gasket.

Ken: get new O-rings! :)

Yes, I have been told we are about to change a complete engine line over to it and the intent is also to carry back. I am talking several hundred thousand units a year.

Seems the curing of the 518 caused some problems and it was less flexible. 5188 gives better results on all the surfaces we have used it on, including oil pump to block and ladderframe to block.

Obvously I havent tried it on a Lotus yet, but cant see why the same improvements cant be beneficial to us Lotus owners.

Cheers

Ralph

Ken:

There is a guy on the USA West Coast who specializes in the 907 used in the Jenson Healy.

He has developed a Valve Cover Gasket set/package he finds will not leak - and is reusable.

Check it out at www.jhps.com

Hope this helps.

Bob
