DannoSupra Posted August 5, 2008 Share Posted August 5, 2008 (edited) Ran into a bit of a problem today when cleaning up Ye Olde valve's. I was a bit wether to get new one's. But the condition of them has helped me choose. If i was keeping the enigne and turbo stock then i'de carry on and keep the old ones, but because im spending so much on the engine i dont want to risk anything. What would you guys recomend? Now OEM are out of the question at £35 Each + Vat. Im not planning on raising the rev's for a start. Any reviews with the Brian Crowler one's, or the PHR? Planning on getting new springs and retainer's too Thanks Here's a few pics of what i found today: Compared to a good one: (Some are worse and some are better) Edited August 5, 2008 by DannoSupra (see edit history) Quote Link to comment Share on other sites More sharing options...

paul mac Posted August 5, 2008 Share Posted August 5, 2008 TBH i cant see a right lot wrong with them mate, i rebuilt a head about 2 years ago that is still going strong and am now rebuiling another so have a good idea what they look like, what exactly are your concerns Quote Link to comment Share on other sites More sharing options...
d_d Posted August 6, 2008 Share Posted August 6, 2008 i agree with paul, they dont look to bad Valves arent cheap anyway really you obviously got the head off are you going to regrind them and your obviously putting new stem seals in?

Nic Posted August 6, 2008 Share Posted August 6, 2008 What would you guys recomend? Now OEM are out of the question at £35 Each + Vat. I'm sure someone would be able to supply cheaper than that Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted August 6, 2008 Share Posted August 6, 2008 What's supposed to be up with them? In an ideal world you would change the valves, caps, cotters and guides as a matter of course, but it's costly! Those valves look OK, how do they measure for stem size? So long as you aren't building some screaming race engine I would say they could well be re usable with no issues, subject to a micrometer check and a straightness check.

DannoSupra Posted August 6, 2008 Author Share Posted August 6, 2008 Cheers for the Advice boys... They're all straight and measure up the same. Been at them with a Vernier Just dont know what to do, so i posted up on here Quote Link to comment Share on other sites More sharing options...
JamieP Posted August 6, 2008 Share Posted August 6, 2008 Whats with the little dent in them then? is that ok? Quote Link to comment Share on other sites More sharing options...
DannoSupra Posted August 6, 2008 Author Share Posted August 6, 2008 Whats with the little dent in them then? is that ok? Thats why im a bit :blink: could be stretched. I'll double check the lengths tomorrow with a digital vernier, cant go wrong then Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted August 6, 2008 Share Posted August 6, 2008 A vernier is nothing like accurate enough for valve stems, you need to use a proper micrometer. They won't be stretched.... Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted August 6, 2008 Share Posted August 6, 2008 I meant for the stem diameter, not o/all length. Quote Link to comment Share on other sites More sharing options...

SimonB Posted August 6, 2008 Share Posted August 6, 2008 Have you got the engine manual? There's a load of checks in there for checking stock valves - diameter, seat width etc etc. Quote Link to comment Share on other sites More sharing options...
