I would not do it myself... better of paying someone for that job everything else is not too bad (injectors, intercooler, 2nd cai etc) and can be done in no time. Valve springs would be the only job I would defiantely leave for some1 else!! Link to comment Share on other sites More sharing options...

You also need a special tool that hooks under the camshaft and winds down to compress each spring enough to get the collets off... This is just what I've read so feel free to correct me guys. Goldie, xlr8ed or m6 xr6t would be the ones to ask...Chris Link to comment Share on other sites More sharing options...

ByeByeRB26 New Member 9 Member For: 18y 8m 22d Posted 18/04/06 11:30 AM Author Share Posted 18/04/06 11:30 AM Thanks for the reply guys,I have worked on many late and old model engines in my time. I also have friends who are qualified mechanics who can help me if I get stuck.Just want to get an idea in whats involved before I start.Performance workshops in sydney are charging in excess of $1000 for this job, I personaly dont see how 4 hours work is worth that kind of money especially when you can get a set of cobra springs from nizpro for $286Any one else have any advise on whats involved in the replacement of valve springs, preferably someone who has done it before.Or someone who can lead me to an old post, possibly with instructions and pictures of the process.Thanks Link to comment Share on other sites More sharing options...

Isn't it enough that we have to pay 1/2 million for a crappy old house. Link to comment Share on other sites More sharing options...

You need 2 special tools, Cam holder and spring tool. together they would be worth around 800.You have to get the engine to TDC with both cams bing in the correct position, then with the cam tool lock them into place, Lock the cam tensioner back in place so it doesnt rachet out, Then undo the cam phasers and in the correct order undo the cam caps. Remove cams, start changing springs. You need compressed air into the cylinder to hold the vavles up. You also need to make sure the crank doesnt turn when you place air in the cylinder. If I was you I would get someone whos done them before, if they are quoting that much try and offer cash and bring them down.ohh also before reinstalling cams remove the lifters and bleed them back keeping them in there correct position you removed them from. hope that helps.
