Hi thanks for your reply.
car has a new rad. When I got the car the rad was in a right Mess -not had her to long Few months. But as seems usual with these cars she’s had a fair bit of neglect.
I did consider pulling the sump to see if she could be saved but decided to just get another engine.
I can then decide what to do with this one.
if she’s not to bad I might do a full rebuild inc porting the head and cutting 3angle valve seats etc to let her breath a bit easier then swop her over again -but that’s pie in the sky till I get her running again

Install starter and exhaust manifolds now, it gets real tight later. BTW, you will need new exhaust manifold gaskets. Do not overtighten the exhaust manifold bolts...there is a reason.

Can't answer, sometimes the depth is critical to the block..pay attention to this. RR is crazy with their hardware. Whenever I do a teardown, I document bolt locations and sometimes have to compare what is there with the factory parts listings for accuracy.

I can pretty much guaranty that all these aftermarket products have not been tested, that's why dealer parts are usually triple the price.
And I can pretty much guarantee you that no wax pellet thermostat has been pre-tested. They're mass manufactured items with an incredibly small failure rate and it would not be cost effective to individually test them.

As an aside, I'll never put a Crewe Original, lead-pellet type thermostat in any of my cars ever again. Talk about nightmares prone to failure from multiple angles. I've seen several stuck open from galling, the one that had been in LRK37110 was missing all of its lead pellets with zero evidence of any overheating incident, and other "interesting" developments. The lead pellets themselves were a band-aid for the galling issue, which should have been solved but never was.

But I agree that one should always do a stove top test on a new thermostat. It's simple to do and gives you lots of peace of mind.
