GT6 Mk3 only runs well with VERY advanced timing. Any ideas why?
johny replied to nicrguy1966's topic in Electrical System
And I thought it was just my other ladies I had to keep secret from the wife! -
Here we are, what do you think Doug?
-
Whats the issue then Tim? I thought its clear a complete mk1 engine has been fitted and the PO just thought as he had a mk3 GT6 it would need the later gasket....
-
Gasket doesnt look recessed in photo above just a normal mk2 fitted to a mk1 engine which wouldnt help its correct location🤔
-
Do all the blocks have the bulges into the pushrod chambers Ian and its just the mk 1 and 2 head gaskets that are different in this area?

Adjustable wishbone bracket?
johny replied to Stratton Jimmer's topic in Chassis, Suspension & Steering
No its alright need to check visually but I think all chassis have the curve... -

Oh ok for a mk2 Vitesse though...

johny replied to Stratton Jimmer's topic in Chassis, Suspension & Steering
I wonder if those brackets arent for converting a GT6 to rotaflex not for one that started like that. The chassis look different with the non rotaflex having a downward curve around the axles which means those brackets are welded onto a non horizontal surface... -
This is interesting from the Triumph service training notes manual and shows the acceptable pump pressure range at cranking revs plus the means to reduce it if too high....
-
Perhaps the free to download Vitesse manual (same doors) at vitessesteve.co.uk would be useful...
-
Surely thats a mk1 block as its got the bulges into the push rod wells that match the mk 1 gasket and which the mk2 gasket doesnt have! The PO must have thought he had a mk2 engine (logical) and used that gasket but it had no chance of working. The mk1 gaskets supplied nowadays dont seem to be copper but a composite....
-
Yes bearings never changed in the gearbox it was just the synchro rings and some gears although ratios stayed same....
-
Yes or it could be overstamped GR after a recon☹️
-
The D type overdrive was used on all models of GT6 as reportedly it never got the layer J type. The gearbox however did have changes so you would need to check its serial number as that should hopefully indicate its internals....

A higher octane fuel would help here with pinking so that the mix doesnt ignite prematurely before the flame front reaches it... -

Cant see it as complete waste of time as valve timing was wrong wasnt it? How much do you think it was out in the end? -
The dreaded spitfire rear hub
johny replied to Doctor slow's topic in Chassis, Suspension & Steering
Looking at it I cant see numbers of splines just their diameter so presumably thats all that matters. If yours are correct for Spitfire they should fit all the small chassis triumphs... -
The dreaded spitfire rear hub
johny replied to Doctor slow's topic in Chassis, Suspension & Steering
Im pretty certain when you buy studs they specify the number of splines to match what you need so theres no deforming required👍 -
The dreaded spitfire rear hub
johny replied to Doctor slow's topic in Chassis, Suspension & Steering
I can only think the splines of the new studs were different or didnt align correctly with the hubs so wouldnt pull in... -
Id be worried about using an insert for a head bolt🤔
-
Is this the right way round? I thought the later engine had the thicker studs. Reckon Tim must have custom made short studs for a mk1 with the diameter to suit the later block😳
-
Yes Canley says dome pistons fitted from KE10001 except US market... It probably would have come with emissions type carbs so maybe someone just installed another head complete with carbs and manifolds?
-
Ah a US re-import might change the story as Triumph did different things across the pond. Even so mixing blocks and heads seems extreme...
-
According to Canley its from KE10001 that got dome pistons so making Tims engine originally one of these😳
-
Unfortunately that list is all mk2 heads so the inline ports head Tim has wont appear in it....
