I had to loosen and turn my oil cooler under the oil filter to get access to the knock sensor and I was wondering if the cooler has a specific clocking when I retighten it? thanks for any info
ok thanks next question ( I am putting two different part car engines together) I swapped heads but the valve train is super noisey... good oil pressure.....I see there is no lash adjustment so does that indicate that I need to replace the lifter inside the rockers or is there something I am missing? thanks
Pre-89 had an anomaly with lifter tap. So if the head you used was from an 88 that could be it. I think in 89 they increased the oil delivery aperture so the factory induced tappet noise was mostly cured. Hope that helped.
Those knock sensors are a complete pain to get to. I wriggle my arm up there from beneath the car and use a mammoth crescent wrench on them. So far so good, but i've only had to change one.
They are HLA's hydraulic, lash, adjusters.
Just let the car idle a while and drive it they should fill will oil and "charge" and the tapping should stop.
How questionable is the engine and head you used, you don't need to floor it but the higher oil pressure form higher RPM's helps charge them.
if after 30-45 minutes there is still tapping then remove the valve cover and find the rocker with play and swap the hla in it.
the "fix" that they used for the lifter tap didn't work by the way. All of my 92's also had lifter tick, as well as several friends with 91's and 92's. even the 93+ 4 cyls had horrible lifter tick after 100k miles.
Lifters wear out, get dirty, etc... Normal. It's not an issue, just maintenance.
