I put in all new lifters into my 2006 Malibu. I locked the timing chaining into place put everything back together and now the car won't start. It turned over acted like it wanted to start and just backfired. What do I need to check? I thought it was flooded so I waited and went back out and tried to start it again and the same thing happened.
Do you have the 2.2 liter Ecotec 4-cylinder engine, the 3.5 liter V6, or the 3.9 liter V6 engine? If you have the 2.2 liter engine, there may be a camshaft/timing chain issue if you skipped a tooth when you put the chain back on the cams. If it's a 3.5 or a 3.9 liter V6, you may have incorrectly installed the push rods back into the engine. 3.5 liter intake push rods are approx 5 3/4" long, while the exhaust push rods are approx 6" long.
The 3.9 liter intake push rods are approx 5.81" long, while the exhaust push rods are approx 6.1" long. If you mix the two lengths up when you put them back in the engine, you're going to have problems.

What motor is it? Some of the V-6's will always make the noise no matter what you do! Gotta love GM for this!
SOURCE: car won't start, wait 15 min. will start but kinda backfires.
possible ignition coil pack breaking down...unit cools off them fires plugs again...fuel pressure is a concern also ..possible failing fuel pump

if its a ticking when you start from cold and goes away soon after start as the engine warms up it is most likely a crack in your exhaust manifold ( you may call it a header in the us) as it is getting the hot exhaust straight from the cylinder it heats up very quickly and closes the crack stopping the ticking. you should be able to get a nechanic to run a weld along the crack easily enough depending on where it is.

That depends on when was the last time the car was serviced and how many miles its done since the last service.
If its a high milage car then having the valves set should clear up the misfire and the lifter tick.

add a litre of diesel and a 3 sec squirt of fairy washing up liquid ,use vehicle for a week and see how it sounds ,if its quietened down a bit ,change the oil and use a cheap diesel engine oil and then add some more diesel and fairy and leave another week ,if it still hasnt quiented down then strip and repair ,is has quietened down the change oil again for good measure and use the diesel engine oil as its a detergent oil and then change oil at approx 6000mile interval no longer and use the cheap oil .Change oil filter every third oil change and you will not get a repeat of the problem.Use an expensive long life oil and the problem will re appear ,because the additives and combustion residues will clog up and stick the hydraulic valve lifters
Testimonial: "TY for the info and hopefully i don't have to tear it down again.(I just replaced lower intake gasket 3 months ago)."
