well done Blue... was the torque setting you went to correct?

Hughes claim it is but I have my doubts. After talking to a couple of engine building pals, 22ftlb seems more appropriate so that's what I've used. We couldn't come up with any good reason to go higher.

worked out ok in the end at least...

I hope you bought a lottery ticket!

oowwuch!
Just a thought ?
Are all the bolts the same length?
Could there be any grease/oil in the hole or and debris?



oh! love that engine bay

Yes all the studs are the same length and threaded by hand into the head to equal depths, oil but no debris. Seriously, 30ftlb on such a small thread has me gritting my teeth, it feels way too much given a lifetimes experience of tightening things up with spanners.

Always best to go on instinct and experience. I always use a torque wrench but often stop short of the recommenced torque settings. I am not sure how accurate some instructions are, particularly on aftermarket parts.

Can't disagree with that!

hhmmm

30ftlb does seem a bit much for a 5/16' = 8mm bolt. When the Ford pinto head bolts are 12mm and the 1st stage of head tighening is 30ftlb for those.

What a F@cker, great work on getting out in one piece

After a quick look round, there seems to be conflicting information on the settings 25 and 30

Yes but they are talking big block which use a larger bolt, Hughes say 40ftlb for those...

Having seen some of the mechanics over here, I’m surprised there’s a torque setting at all. I watch these guys work and they seem to operate on “time on impact” settings. They refer to them as Ugga Dugga’s.

oopss thought you were big block

Ah! should have paid more attention to where your distributor was

Blimey a year since the last update! Much has changed, Covid,retirement and moving to a smaller workshop for a start. After a bit of a think it was time to let the Valiant go, well some of it at least. Engine I am keeping and the four speed set up I will sell Separately. Royden has bought the car so it’s not going far, it goes in for paint in 2 weeks time and then I will be fitting another 408 with an auto trans. No doubt I’ll still get to drive the car so it’s all good.
