WWT338J Posted October 26, 2020 Report Share Posted October 26, 2020 Wise men, I have an annoying persistent minor oil leak from somewhere near the back of my cylinder head gasket following a head removal some years ago when I had unleaded valve seats inserted and the head resurfaced. I used a Payen gasket and have always used Payen gaskets in the past. I'm planning to replace the gasket and wondered about a Lucas gasket. The thin bead of silicone around the perimeter looks appealing. I realise "Lucas" has nothing to do with the Lucas of old. I've never seen these gaskets advertised in the UK despite the (US) claim that they are made in the UK. Has anyone tried these gaskets? Thanks David Quote Link to post Share on other sites

That gasket looks to me to be a Reinz or Elring gasket with that silicone beading, made in Germany. They were a competitors of Coopers - Payen. There is nothing wrong with their products except the price which is always on the high side as German companies know how to charge. They do not go in for low mark ups they like their 1000%!!!! But if you have taken your Cyl. head off I would check it for flatness as most TR heads warp??? That may have been an original problem.

John L Posted October 26, 2020 Report Share Posted October 26, 2020 I'm a fan of the old Payen copper gasket, as the all the holes in the copper is rolled over and so there is no seep thru the gasket itself. Pushrod side will be sealed better. Heritage Gaskets still have some of these gaskets at £ 20 +p&p http://www.heritagegasketsltd.co.uk/products/4588089187/triumph-payen-ref-no-ae350/9368918 I think its only for the early blocks NOT recessed There website is not up to date including prices, also good manifold gasket as well!

John Hi John. The trouble is that the copper top and bottom gaskets have a white asbestos layer in between which is toxic. Even in my day day in the late 60's and early 70's Coopers- Payen were moving away from the use of White asbestos, for all the health and safety restriction's. Unfortunately some of the apprentices that I worked with have since died of asbestos related deceases. Bruce Quote Link to post Share on other sites
PodOne Posted October 26, 2020 Report Share Posted October 26, 2020 The "Lucas" looks like a good gasket with silicone in the right places to deal with the leak issues discussed in past threads around the push rod galleries. Is there a UK supplier and what's the cost v the Payen gasket which seems to benefit from a bead of sealer come fitting time to prevent leaks. Is the Lucas worth the extra?

fumblefingas Posted October 26, 2020 Report Share Posted October 26, 2020 I have one not installed yet, sure looks quality. Still sitting on my washing machine. That's mine in the pic David.

John McCormack Posted October 27, 2020 Report Share Posted October 27, 2020 On the issue of the oil leak near the rear of the head. There is a common oil leak on TR6s, a thin smear of oil coming from above the metering unit. Mine does it, it rarely if ever is bad enough for the thin smear to reach the bottom of the block before I wash the engine down. An occasional engine wash fixes it cheaply and effectively without having the car off the road. Quote Link to post Share on other sites

John John, You've mentioned your success at purchasing Payen gaskets from Heritage recently on another thread. I'd be pleased to know how you managed to contact them. I've tried umpteen times over last 2 - 3 months without success. Do you have an alternative means of communicating with them? Dave McD Quote Link to post Share on other sites
DRD Posted October 29, 2020 Report Share Posted October 29, 2020 The company that rebuilt my engine said that they no longer use Payet head gaskets as they've had problems with them in the past. Quote Link to post Share on other sites
PodOne Posted October 29, 2020 Report Share Posted October 29, 2020 I used to use cometic head gaskets for my MX5 boosted motors running silly bhp's and never had any issues. Not cheap but used to do a group buy to keep cost down with other folk. They offer a TR6 gasket for non recessed block here https://www.cometic.com/applications/v-twin/triumph/tr6/1969 might be better than the Lucas offering. Andy Quote Link to post Share on other sites

roy53 Posted November 1, 2020 Report Share Posted November 1, 2020 i believe that the TR shop sell one that has the red silicon beads as an upgraded version . Not used one though Roy Quote Link to post Share on other sites

I think they said the gasket they use is about £100. I think that you will find that they use a Victor Reinz Gasket that sells in the UK for around £150 each!! As I have never had an oil leak from the back of the cylinder head or a blow between the bores. I always ensure the head is not warped, as this is a well known problem on early engines, checked with an engineer's straight edge. Re-torque after 500 miles. I will keep using the genuine Payen Gasket which are now made by Fel-Pro the largest gasket manufacture in the world. Bruce. Quote Link to post Share on other sites
