Anyone know the part number for the plug ?I am looking at the Cadillac Catera with many interchange-able part (if not all!) and it is as follows,
Bit of a update peeps, i took the pleneum off tonight and it stunk of petrol,i also found that it wasn'tsitting properly. all put back together but still have same problem ,i,ve also noticed that the chrome pipe in front of the drive belt gets red hot !! can any one explain why is this??? it has also blown the short rubber pipe it connects onto,could this be the problem??If I am not mistaken those are the exhaust gases coming forward. There is obviously exhaust pressure (misfires, blockage, failure of the SAI one way valve on the SAI pipe, etc.). It may be related to your overall stuff but it is quite disturbing!
Couldn't the wheel size change mess up your speedo and odometer!Quote330mm discs went under 17s on the ST, but if you are going V8 than surely the wheels would be either 18 or 19's?I am looking to go to 18" Ronals so anything that will go inside those is good. I think that for purpose the discs need to go bigger with more pistons in the caliper too?
362mm on the VXR vectra needs 19's
Replacement carriers are generally sold as part of the upgrade kit fairly sure if you are modifying the engine bay to fit a V8 adjusting a couple of caliper carriers will be childs play!
Guess it all depends if you want more area and more pistons or same area and more pistons?
Another thing that will need checking is bore size on the replacement discs as i would assume FWD front hubs have a different bore??
Right at the front of the engine, to the left of the battery, is a small almost S shaped hose, seems to be "sucking in air" from the small crack in it, replacement on order but can I still drive it ok? Sorry I'm so crap with anything mechanicalPerhaps you can pinpoint in the picture,
Battery and charging system A.o.k.Looks like change of plugs then coils.May perhaps check what is in the following before anything else,
Misfire only at idle.Accelerates fine.Electrical system is most stressed at idle. Battery, charging system, weak coils or marginal/fouled plugs in my opinion.
QuoteYep, its 25Nm.Now he tells us, just did mine at the weekend, 25nm. 30k since fitting. Had a miss fire/ grumpy start last week,only did it once, pedal trick revealed 0300 and 0304. Sure enough, cylinder 4 was loose to the point I could undo spark plug by hand with soot all round the base
When fitting I torque them all up and then go round them all again as often the washer has relaxed
Changed them all anyway but I didn't go over them to re torque again.
Difference between books and Experience , you cannot teach experience.
Blow through the pipes to make sure they are clear.
But, all engines with have fumes visable udner such conditions due to blow by gases
or concern :-? at times. I have finished so far jobs on this car for timing belt, water pump, coolant flush, aux belt, aux tensioner, crankshaft pulley, oil pressure switch, alternator overdrive pulley, all brakes with front GTO swap and brake fluid refresh, rear coils and shocks, breather clean, throttle clean and normal oil and filter. Almost all these with information and help from this forum.
