Pig Posted June 17, 2006 Share Posted June 17, 2006 I had a leak down test done today and the results were: 1 93 2 89 3 92 4 94 5 94 6 88 Ok so no.6 isnt great but its an old engine on 110,000 So my next plan of action is: Valve stem oil seals valves and tappets sorted and head skimmed when they are being done. boost logic 650 injectors boost controller - the colourful blitz one Aeromotive FPR Oil Catch tank Breater pipes plumbed into correct places Heat shield for my air filter chris wilson pads goodridge hoses + the future motorsport prize i wont at the DB06 (i cant remember what it is though) I think that just about covers it for now. Then i plan to run that at 1.2 bar and have an option for 1.4 on the boost controller for cold days and ferrari killing moments (providing the engine seems to cope with 1.4) until i can afford a new uprated bottom end. With regards the late boost problem, i hope this will be sorted by this work being done. If not we will start hunting again. Good news for me though as i was planning to take the car off the road to save for the rebuild Looks like you wont be getting rid of mr and mrs pig just yet Quote Link to comment Share on other sites More sharing options...
Whitesupraboy2 Posted June 17, 2006 Share Posted June 17, 2006 sorry im trying to learn this stuff, is a leak down test same as a compression test? Quote Link to comment Share on other sites More sharing options...
Pig Posted June 17, 2006 Author Share Posted June 17, 2006 Nope, AFAIK 2 different tests. This one would have shown me if i had killed a piston ring etc Quote Link to comment Share on other sites More sharing options...

Gordon F Posted June 17, 2006 Share Posted June 17, 2006 If you are taking the head off it will be worth your while to have new valve guides fitted as well as seals. Quote Link to comment Share on other sites More sharing options...
Robert Posted June 17, 2006 Share Posted June 17, 2006 good news on your car mate, did you go upto phoenix? Quote Link to comment Share on other sites More sharing options...
letmeshowyou Posted June 18, 2006 Share Posted June 18, 2006 Jon - what should figures should a stock engine be giving, any ideas? Quote Link to comment Share on other sites More sharing options...
Pig Posted June 18, 2006 Author Share Posted June 18, 2006 Yep, i went up to pheonix. Mark will be doing the work on the car. I think it depends on how many miles the engine has done. On average miles i wouldnt expect less than 90 mate. 88 is on the low side, hence that i will be saving for a new bottom end! Quote Link to comment Share on other sites More sharing options...
Pig Posted June 18, 2006 Author Share Posted June 18, 2006 If you are taking the head off it will be worth your while to have new valve guides fitted as well as seals. Really?? Mark didnt mention this to me! Were talking along the lines or re-building the top, so the head will be coming off! Quote Link to comment Share on other sites More sharing options...

skaeley Posted June 25, 2006 Share Posted June 25, 2006 Guys, Any idea how much and the best place to get the Valve Stem Seals done ? Quote Link to comment Share on other sites More sharing options...
Pig Posted June 25, 2006 Author Share Posted June 25, 2006 Prob looking at about 600 i think, where are you in the country? Get in touch with the traders! Quote Link to comment Share on other sites More sharing options...
Lucifer Posted June 25, 2006 Share Posted June 25, 2006 Head on or off the car? Stem seals will only mask worn guides. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted June 25, 2006 Share Posted June 25, 2006 I had a leak down test done today and the results were: 1 93 2 89 3 92 4 94 5 94 6 88 Ok so no.6 isnt great but its an old engine on 110,000 I don't get those figures, leakdown tests are usually shown as a percentage figure, with a freshly buil race engine showing mayber 2 or 3 % and a just about running old nail about 30%.

Ian C Posted June 25, 2006 Share Posted June 25, 2006 It's %age left in cylinder, so for example cylinder 6 is 12% lossy. -Ian Quote Link to comment Share on other sites More sharing options...
Ray Posted June 25, 2006 Share Posted June 25, 2006 How much does it cost to perform this test? Might be a good idea before i think about going single ehhh... Quote Link to comment Share on other sites More sharing options...
Pig Posted June 25, 2006 Author Share Posted June 25, 2006 It would be a good idea! About 2 hours labour mate! Cost me £80. Thinkig of going single? wanna swap cars? Single all done, just needs the lag problem sorted! Quote Link to comment Share on other sites More sharing options...
Alex Posted June 26, 2006 Share Posted June 26, 2006 It's %age left in cylinder, so for example cylinder 6 is 12% lossy. -Ian So that 4x as much loss in cylinder 1 as there should be? Sounds a bit dodgy. Quote Link to comment Share on other sites More sharing options...
Pig Posted June 26, 2006 Author Share Posted June 26, 2006 You get the extra loss over age. Those figures are pretty much whats expected of an engine with 100k on it! Quote Link to comment Share on other sites More sharing options...
