Way back in 1996, when my local machine shop and I were learning the TR3 =
engine together, he laughed at the felt strips and pulled down a dusty, =
ancient box of sealing =E2=80=9Crope=E2=80=9D off a top shelf. We soaked =
it in Indian Head shellac and hammered it tightly into the void. I had =
plenty of other problems with that engine but leaking around the rear =
main cap wasn=E2=80=99t one of them.=20
=20
Rather than leave you wondering I struggle mightily with head gasket =
failures. That is why I am so talented at replacing them to this day. =

because the threads in the block I had were compromised. It finally =
called out to me with a couple of cracks on the water jacket side; =

I also have the center plug hole on the main oil galley tapped to =

Have the shop check the alignment of the mains and line hone if =
necessary.
Machine the center main cap to install a reinforcing strap.

Hello All,
I disassembled my TR4 race car engine this past week. Last time I =
rebuilt it was 1987. Last time I raced it was 1988. Probably had five or =
six race weekends on the engine but its been sitting for almost twenty =
years! It is amazing everything looks very good. Rod and Main bearings =
show minimal ware and the same with the pistons and liners. G3 cam and =
followers including head and valves all look good. Cam bearings look =
questionable...
=20
So I plan on installing new cam bearings, Rods & Mains. Any suggestions =
as to what brand and where to buy them?
I will deck the block. Any suggestions as to other machining I should do =
to the block?=20
=20
The crank looks fine but I haven't measured it yet. What clearances =
should I run?
I do plan on balancing and polishing it.
=20
Thanks for any input.
