TR2/3/3A tr3 head gasket

Share this page

Sorry I have to disagree if I understand this post correct. You always need the liners protruding above the block, so the liner hits the gasket correct for the seal or you will blow the gasket.

Reading theOwners Hand book they say .003-.005 after removing the head at 5k for decarbonizing.
I was just thinking the measurement of the initial assembly would be higher than when head is later removed.
Thanks
Tom
 
Thanks.For now this is a head gasket replacement and valve job.I am not going to pull the liners so I am going to try what I have,which looks like about .001-.002'.Hopefully with some proprer re-torquing I will get at least another 20k.

Unfortunatelly my gasket job has been put on hold.
I finished the head yesterday and today ready to install I realized the Moss gasket is in my opinion not useable.Its the copper clad/composite but the holes for the liners are not even round.They are kind of squared off on the lifter side with about an 1/8+ of liner showing with no gasket contact,86mm.
Anybody seen this before.The old copper/clad liner holes are round.
Any us source for gasket of better quality?
Thanks
Tom
 
I was going to order the Racetoration gasket but looking at the web site pic I can clearly see the liner holes are also far from round and would not fulluy cover the liners.
I sent moss a pic and they are going to get back to me.
I spoke to chris at rimmers and he said looking at their pics ,their gaskets seemed also not round for the liner hole and maybe this is on purpose rather than sloppy tooling.
He also saidTEd Shumacher at TSimports might knowbut I got his machine.
Am I missing something?old gasket holes are round,but I cant think of any reason the new gasket would not fully cover liners.
Thanks
Tom
 
Those head gaskets seem to get worse all time. I think you will be ok with some protrusion and some kind of sealer. I used copper coat spray. The copper coat was sticky, but when I pulled the head off after a cam failure the head came off with no problem, so my fear of never getting the head off again did not happen. There are only so many venders and probably not many manufactures of the head gaskets. I called BPNW because they are close to where I live and went for it. The gasket was off in many places and I did not like it, but at some point we are stuck with these guys. I do remember the main holes where not round or something too.

Thanks Steve.
The more I look at it the more I think I should just put it together.The similar one that I removed looks better but its been compressed.
The rimmers /Bastuck pic that popeye posted looks better but you still see the distortion by the lifter openings.

Tom,
I am planning on installing my head this weekend. I'll take and post some photos of a copper gasket from TRF as well as the "fancy" gasket from Rimmers.
 
Mike, I'd guess the Rimmer Bros. one will still surround the liner tops totally. And if you do use the TRF one, Permatex copper spray!!

EDIT: Use the spray on ANY of 'em.

Thanks! I plan on using the Rimmer gasket with the copper spray. I had the thinner TRF one as part of a complete set of gaskets, and used it to trial fit the head and make sure the liners were fully seated.

Top photo is the “basic” copper gasket from TRF, bottom the Payen from across the pond. Both are not round around the cylinders - almost like on purpose?? However it seems there is plenty of “meat” of the sleeve under the gasket.

(And none too happy about the scratch on the Payen by cylinder #2… argh.)

Thanks mike that would be much appreciated.
I talked to Chris from rimmers today and although working from home and not able to look at one directly he could see in the catalog pic not round shape but wasnt sure if it was intentional.
I said i would call monday to order if I couldnt find anything quicker than about 10 days courier.
I may be overly about something that will still work fine

Thanks for posting the pics.
 
The "odd" shape of the gaskets is to accommodate the valves at full open.

That may be,but it doesnt make sense to me.
The valves on my head would need 5/8" lift to to come even with head bottom,plus the valves are within the combustion chamber so L am not sure how this would accommodate the valves.The intake valve is closer to the edge if the combustion chamber.

Another observation is the coolant holes that appear to be out of position on the block but lineup with the head.
The only way I can see to improve flow would be to relieve the block,but seems this would remove metal toward the head stud which I believe can be prone to cracking so I wont do anything but wondering if others have.
The more I look , the more I think I should put it together.
Thanks for all the responses and pics,Im here to learn,and this sites members have been great for that now,and when I was building the car.

Not so much as a clearance for the valves themselves, but rather to allow better flow of the gasses going in and out of the ports more efficiently. There's no valve interference involved.
 
Thanks Dr.
Like the block water holes that look off ,but right on the head,you got me thinking I also needed to look at he gasket on the head and I can see what you mean.
Thanks
Tom
 
Just to add a bit more info to the subject. I have several head gaskets on my shelf. There are three different ones. (1) I bought from a mechanic at a business closeout about 8 years ago. (2) is Bastuck/AE330/PAYEN.
(3) is a more recent purchase from TRF.
1&2 are not round while 3 looks almost round.
Measurements were
1 -3.14" x 3.145"
2 -3.42" x 3.43"
3 -3.475" x 3.49"

Thanks Charley,Dr Entropy got to see the that I needed to look at how it matches the combustion chamber,not the liners.
Thanks
