Martin White Posted October 16, 2020 Report Share Posted October 16, 2020 Hi Folks Just had the cylinder head gasket blow on my 1500 spitfire (lots of white smoke). Does anyone know where I can source a high quality cylinder head gasket set? Did look at K seal but decided to do the job properly but want to make sure that the gasket that goes on is as good as can be. Thanks Link to comment Share on other sites More sharing options...
Clive Posted October 16, 2020 Report Share Posted October 16, 2020 Payen were to best. Heard various things about the latest production, mainly 6 cylinder gaskets but worth checking. But I would be looking for a NoS Payen. Just not the very latest stock. Link to comment Share on other sites More sharing options...
Martin White Posted October 16, 2020 Author Report Share Posted October 16, 2020 Thanks Clive. Can you elaborate on the NoS Payen not the latest stock comment please? Link to comment Share on other sites More sharing options...
wimpus Posted October 16, 2020 Report Share Posted October 16, 2020 Bought a new Payen one for a 1500 in july (after 42 years/306.000kms it needed a head rebuild and new gasket). Now the car had done another +6000km with the new gasket and is fine. Link to comment Share on other sites More sharing options...
Martin White Posted October 16, 2020 Author Report Share Posted October 16, 2020 Doing slightly better than me. Took delivery of new car at 11.30 on Tuesday and head gasket blew at 4.30 same day :-). Thought I might get at least one day before I had to get my hands dirty! Shame really as was really enjoying driving around in a Spit again after 30 years of owning one. Have the luxury this time of a dry and relatively warm garage to work in. Just hoping head gasket is the issue. Link to comment Share on other sites More sharing options...
NonMember Posted October 16, 2020 Report Share Posted October 16, 2020 I bought one from Canley last year and not had any trouble yet, but then the car's not had much use due to fuel tank issues. While you've got the head off it's probably worth replacing the studs and nuts, maybe change to the MiniSpares flanged nuts with the integral "washer".

68vitesse Posted October 16, 2020 Report Share Posted October 16, 2020 If looking at NOS check what is actually in the packet, it is not unknown for partially used sets to be made up with ones of questionable quality. Regards Paul Link to comment Share on other sites More sharing options...

Sparky_Spit Posted October 16, 2020 Report Share Posted October 16, 2020 I have a 1500 Payen head gasket on back order with Paddocks. They tell me that their supplier is waiting for more to be manufactured. I'm not sure if that is good or bad news? Link to comment Share on other sites More sharing options...
Clive Posted October 16, 2020 Report Share Posted October 16, 2020 4 hours ago, Martin White said: Thanks Clive. Can you elaborate on the NoS Payen not the latest stock comment please? It appears payen have moved factory/country of manufacture, and the latest stuff possibly isn't as accurately cut? I would happily buy an ebay set from a reliable seller. Check the gasket has the "tag" on it, that shows it is for recessed bores. And about replacing studs etc. I never have. However NEVER swap the washers unless you have bought the correct hardened type (normal ones will slowly squash and lose torque=blown gasket). The flanged mini head nuts are a good idea, sensibly priced and correct grade Link to comment Share on other sites More sharing options...
Nick Jones Posted October 16, 2020 Report Share Posted October 16, 2020 +1 for the flanged nuts from Minispares. I’d consider those essential. The studs should go again unless obviously damaged. Does it seem that the head might have been off recently? What symptoms other than white smoke? Header tank like a jacuzzi and smelling of fumes? Water loss? Loss of compression? Does the car have a brake servo fitted? Nick Link to comment Share on other sites More sharing options...
Pete Lewis Posted October 16, 2020 Report Share Posted October 16, 2020 and do clean/ run a die nut down to clear the stud threads and +1 for mini nuts cheap and far better than the soft washer problem Pete Link to comment Share on other sites More sharing options...
Martin White Posted October 16, 2020 Author Report Share Posted October 16, 2020 Seem to have not much water in the radiator but water in the header tank. Oil is clean, no particular weird smell. Car starts OK still and drives (although only to move it to tow truck and into garage). Unfortunately will not have time to look at this weekend as away but will start the process next week. Is it worth filling up with water again to see if I have any bubbles in the radiator/header tank? Anything else I should check before dismantling? As I say I have had the car less than a week is there anything else to check while the head is off. Check seals of valves with petrol, grind the valves back in? I have to admit to being a bit rusty on the maintenance front and probably 30 years since I have taken the head off s spit. Link to comment Share on other sites More sharing options...
Martin White Posted October 16, 2020 Author Report Share Posted October 16, 2020 No brake servo fitted as far as I am aware Link to comment Share on other sites More sharing options...
NonMember Posted October 16, 2020 Report Share Posted October 16, 2020 I wouldn't start dismantling the head unless you discover some horrors. No harm doing the valve leak test but unless it's an obvious fail I'd leave it at that and not do any grinding in. Link to comment Share on other sites More sharing options...

Martin White Posted October 20, 2020 Author Report Share Posted October 20, 2020 Excuse my ignorance but do I need to change the studs, nuts and washers when changing cylinder head gasket? Best place to buy these is minispares website?? thanks Link to comment Share on other sites More sharing options...
johny Posted October 20, 2020 Report Share Posted October 20, 2020 no, studs are reuseable if in good nick but the washers can become dished over time so people replace them with mini combined nut/washer items which are beefier. Link to comment Share on other sites More sharing options...
NonMember Posted October 20, 2020 Report Share Posted October 20, 2020 No, you don't necessarily need to, but if there's any sign of worn threads it's worth it. Make sure you get the proper ones, though. The nuts from the MiniSpares website are a good option - I used them on my Mk1 Vitesse (along with some new studs) and it fixed the recurring blown head gasket every 18 months problem that it had.

Anglefire Posted October 21, 2020 Report Share Posted October 21, 2020 I fitted a new head gasket when I had the head rebuilt (PO of the engine had reground the valves and it was burning a fair amount of oil so had the head unleaded and it was found that the seats had regressed) - and it lasted a few miles - found there was damage - either at the factory or elsewhere that allowed water between the 4/3 cylinders and the water way - was a Payen one - replaced it with another Payen and flanged nuts - I also changed the studs, but that was more that a couple where not in fantastic condition and that I wanted to be sure it had the best chance! But as others have said, Payen doesn't seem to be the same company anymore. Link to comment Share on other sites More sharing options...

poppyman Posted October 22, 2020 Report Share Posted October 22, 2020 Are you sure it is the head gasket Martin? Just take take the plugs out and see what colour they are. Also does the white smoke dissapear quick or does it hang around. What is the temp gauge reading? Tony. Link to comment Share on other sites More sharing options...
Pete Lewis Posted October 22, 2020 Report Share Posted October 22, 2020 Agree it wont be the first time a major rebuild was found to be really just contaminated fuel have you had any disappearing coolant with no obvious leaks Pete Link to comment Share on other sites More sharing options...
Roger K Posted October 23, 2020 Report Share Posted October 23, 2020 If you have a head gasket fail it's always a good idea to check the block deck and head face for flat with a good quality straight edge and feeler gauges. Sometimes head gaskets fail for a reason! Link to comment Share on other sites More sharing options...
