barrytr4 Posted May 14, 2021 Author Report Share Posted May 14, 2021 Hi chaps--I bought a head gasket off ebay a month or more ago, for the Tr4 2200cc only just checked it , the stud holes are for ( Tractor or vanguard) 7/16" studs not 1/2" I have used them plenty of times for 2200cc 1/2" studs engines ( but this time I have bubbles ) what's the concensus ? update just measured gasket stud holes they are about 1/2"bore (no clearance ?) ),,,, bore hole about 89mm, that maybe too big? Thanks ----Barry Quote Link to post Share on other sites

Hamish Posted May 14, 2021 Report Share Posted May 14, 2021 looks like this one ? copper https://www.autosurplus.com.au/triumph-tr3-tr4-tr4a-head-gasket-1955-1967 do the 89mm bores really fit to this gasket ? Quote Link to post Share on other sites
Motorsport Mickey Posted May 14, 2021 Report Share Posted May 14, 2021 (edited) Hhmmmm don’t know how a 7/16th stud Vanguard engine would locate these gaskets if the stud holes are 1/2”. Sounds like a recipe for a misaligned gasket if fitted. If the stud holes are 1/2” ( even if barely) I suppose you could “relieve” them a little with a round file to fit, but you really need the gasket to slide down the studs rather than sticking. As for the gasket working on 89mm bores and suiting a V8 that would tie in with a V8 Rover piston ( my first 4 cylinder championship was won using them in the engine) but using a cut steel head gasket. It’s a mistake to use an overly large cylinder bore gasket, the burning fuel charge get’s compressed between head and block and “squished” into the gasket with the close fitting surfaces preventing it’s dispersement and cooling. That causes gasket burning. You can get away with a 87mm piston in the standard copper size gasket used to suit the 86mm bore, it has enough gasket clearance and the incoming fuel charge cools the copper gasket down. I suppose you’ve retorqued the head down to 105 lb ft having done between 200 and 1000 miles Barry ? Mick Richards Edited May 14, 2021 by Motorsport Mickey Quote Link to post Share on other sites
Hamish Posted May 14, 2021 Report Share Posted May 14, 2021 it doesn't say V8 it says OHV 8v thus i read it as an 8 valve generic description. not that it makes that much difference in this instance i suppose Quote Link to post Share on other sites

He thinks it is a V8 fit and I can’t find a V8 or OHV notation on it anywhere. Mick Richards Quote Link to post Share on other sites
barrytr4 Posted May 14, 2021 Author Report Share Posted May 14, 2021 Hi Chums--Yes, that's the one in the link, Yes 8V, not v8, sorry, I have been thinking about it, and it should be OK? the liners would be thick enough to locate the extra diameter, I can't see any difference if it was the same dia' as the liner bore ? only a bit of space where carbon could build up have a spare liner here will offer it up and see how it looks, get back later--Barry-- Quote Link to post Share on other sites
barrytr4 Posted May 15, 2021 Author Report Share Posted May 15, 2021 Hi Chums checked gasket w/ a liner, the dia of the gasket is about 1mm in from dia' of liner bore,w/ plenty of liner thickness where the gasket sits I think that is OK?, if it were the other way round, ie, the gasket edge in the combustion area it could be damaged? , just noticed has " Stanpart" and a part No 202203 on it , not that would mean anything--Barry Quote Link to post Share on other sites
Lebro Posted May 15, 2021 Report Share Posted May 15, 2021 205481 would be the ST No. for an 86mm gasket, & 202127 for 83mm ( ST spares books TR2 - 4A) Bob. Quote Link to post Share on other sites

barrytr4 Posted May 17, 2021 Author Report Share Posted May 17, 2021 Hi mates--I got the info' on the " 202203 head gasket" it's for a 2200 vanguard Ensign Delux' " same bore as the TR4 but 7/16 studs--should be OK?-----Barry Quote Link to post Share on other sites
Motorsport Mickey Posted May 17, 2021 Report Share Posted May 17, 2021 Barry, Don’t know how to get an answer on this... HAVE YOU RETORQUED THE HEAD DOWN TO 105 LBs FT SINCE THE ENGINE HAD DONE BETWEEN 200-1000 MILES SINCE ENGINE BUILD ? You may sort your problem by doing this.
