Re: Blue's Valiant
well done Blue... was the torque setting you went to correct?

Re: Blue's Valiant
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.

Re: Blue's Valiant
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

Re: Blue's Valiant
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.

Re: Blue's Valiant
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.
Re: Blue's Valiant
Can't disagree with that!

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
Re: Blue's Valiant
After a quick look round, there seems to be conflicting information on the settings 25 and 30
But this page is worth a read

Re: Blue's Valiant
Yes but they are talking big block which use a larger bolt, Hughes say 40ftlb for those...

Re: Blue's Valiant
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.
I am coming to believe a 56mph speed record is harder to achieve than a 400mph one!
Re: Blue's Valiant
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.
