Hey guys, I have have bought a BF gas + turbo motor a while ago, and the seller claimed that it has performance valve springs (Crows Cams) and some other goodies in it. It also came with a turbo exhaust manifold, turbo, external wastegate, intake plenum, etc. so seemed legit and I didn't check what's inside. Now I have finally opened the valve cover and did not find the promissed plazmaman head studs 😱, so I suspect valve springs may also be stock... 😱 Could you please suggest a way to identify if my springs are stock or indeed performance...?

After a bit of advice, I've had this issue for a few years and the fuel consumption is making me want to fix it. This all started about 4 years ago and have just put up with it but the fuel is getting worse, currently getting about 350km around town driving moderately (I used to get 450km driving the same way...). When the engine starts cold it will sound like there is a miss for the first 3-4 minutes. The exhaust has white smoke, very faint though with a very small hint of blue (sometimes). Though the engine oil barely drops between servicing (I change the oil every 10-15k). After 3-4 minutes of warming up the car drives fine, no loss of power. I recently drove a 3,000km hwy trip and noticed the back of the car was full of oil, obviously from overtaking and putting the foot down. Things I've checked: new spark plugs Checked all coils (using servicable one, replacing one by one) Re-flashing the ecu (I have 3 maps and tried them all) Replaced the PCV Checked all hoses visually Compression check I'm suspecting a valve seal is gone or valve spring. My next move is to take the head off and get it recon.. though hoping someone here has a more likely cause, I.e if its the springs or seals would it be worth changing them first rather than take head off? The car is an xr6t mkII with 200,000km, 330rwkw and was tuned 7 years ago running 14psi. I've driven in pretty hard and only since this problem have eased off a bit on the lead foot.

Hey all sorry if this has been answered before but I did a search and nothing popped up, so I've had my fg for a while now and I've finally got it booked in for mods. Im getting xforce exhaust, nizpro cooler and piping, 1150cc injectors, cool air intake and a fuel pump. My question is with these mods will I require new valve springs? Im going to ask for a safe tune but if ttheresa high risk I would rather save for the springs aswell as im guessing they would be a pricey install. Thanks in advance for your advice!

Hi guys, I have been informed that I'm able to use XR8 valve springs in the XR6 Turbo engine, my question is would it be the Barra V8 or the Boss V8? I'm pretty sure my valve springs are shot, my car is standard apart from a front mount intercooler. When it gets to 2nd and 3rd gear in the higher RPM range it seems to want to stall and shudder. I've replaced my coils, I've cleaned my boost solenoid, tightened the exhaust manifold, but the problem is still there. The funny thing is it only started doing it when I changed the fuel filter, but I don't think that's the problem. First gear there's no problems with the car, it revs right out with no shudder or problems. I have also fitted stock rims on the back of it, I know it might sound stupid but do you think that could be doing anything to the traction control? I run the vehicle without traction control. The only thing I can think of is valve springs, I give the car a hard time but it hasn't been boosted or tuned, it's got 170,000kms. Also if I have to go to the trouble of replacing the valve springs, I was thinking of replacing the whole head with an FG head because I would prefer the better intake manifold and obviously the better head and valve springs, but will an FG head fit on a BA bottom end? Thanks, sorry to go on about it but I'm trying to weigh up my options. Opinions and advice would be much appreciated. Cheers
