My P6 V8 engine not sounding great. Quite loud ticking noise. Doesnt overheat, and oil has been changed recently. Any advice?
Thanks! Is that a big job? I know nothing about fixing shit on cars lolMine had badly worn rocker shafts and rockers when I got it. Replaced with after market shafts and rockers from Island 4x4, quiet. I can just hear maybe one lifter ticking while under the bonnet, but nothing audible from inside. If you do the rockers, probe the oil supply hole at the front of each head to ensure its clear.
Well. It was owned for MANY years by an elderly gentleman, who sadly died. No service history was recovered by the family, unfortunately. What we do know, is that he obtained MOT's for every year, even though, of course, not needed. Apart from the noisy engine, the oil guage is not working and its a bitch to start in the morning!.. Genuine 77000 miles.What distance has your engine covered? Has it ever been rebuilt, and if so, what was done?

Worn lifters or it could be the lifters were done before without having the preload set (shims under the rockers).

If it had no oil pressure, it wouldnt get further than the next street..Oil gauge not working would worry me a lot - maybe its noisy because it has NO oil pressure??? Get somebody to check that before running it much anymore!!!
Looks clean but dry, RonIf it has covered only 77,000 since new, then maybe the oil changes were less than ideal. Tapping sometimes occurs when one or more lifters no longer rotate. Now the camshaft lobe strikes them, causing the tapping sound, rather then the correct way of operating by rotating and following the lobe continuously.
Check the colour inside the rocker cover by removing the oil filler cap. What colour do you see, black?

The rust forming on the rocker shaft may indicate an oil supply issue. Maybe pull the rocker covers and ensure oil is getting to the rockers when running.If it had no oil pressure, it wouldnt get further than the next street..
