I have an 01 MT and put an 02 SC'd engine in. i bought the motor from a guy who had stuffed it into an S12 and did a fresh rebuild, i have zero reason to speculate it was done incorrectly, and i 100% believe it is good and has 0 miles on it. just age. i bought the truck with no motor in the summer of 14 and have been working on it slowly and have finally put it together and started it and backed it out of the garage. i have a crappy build thread in here somewhere.

So anyways, here is my problem/concern. there is a tick. its coming from the passenger side cylinder bank, from the rear piston(ish) area. the sound goes away as soon as you raise the rpm above idle. however, i pulled the valve cover and the valve cover and rocker arms were dry on the rear side of the cylinder head. i haven't put the front diff in yet, because i was going to pull the pan back down and check the oil pick up tube. My oil light is also on, however i cannot locate the OPS, or the harness that plugs into it. the passenger side of the block has the block off plate and the oil filer is on the front of the block. there is no sensor at either of these two locations.

Any thought? where/what to look at? i know some of you guys might have an answer for me, just hope you read this.

Thanks

The fact that the tick goes away with a little rpm points to an oil pump/pressure problem.

You spin the oil pump a little faster, the pressure and flow go up, the tick goes away. Does the oil light go out?

The light never goes out. which is why i am wondering if there is an OPS in there, i really need to just go get an aftermarket oil pressure gauge, and utilize the bolt hole in the filter housind. that way, the light wnt make a difference... But, im broke, as usual and dont have an extra $100+ to go throw at a good gauge and everything you need to mount it.

The tick at idle is a sure sign that the oil pressure is low enough to have a physical impact. If you keep running it, could result in engine damage.

dug into this again the other day, charged the battery and changed the oil. it started right up. tick was still there. i added some marvel mystery oil in the oil and ill see what happens when i start it up again.

Come to find out, there is no OPS on the filter housing. there is just a plug filling the hole so i ordered a new one. should be here today. hopefully the light goes out lol. i don't see why it wouldn't, when i took the valve cover off to look for the noise, i started it and oil shot everywhere. but, i definitely found out where the noise was coming from.

a loose spark plug can sound like lifter tick, and will improve as the engine warms up. Most likely you can witness the plug wire moving slightly at an idle if this is the case. Sometimes when an engine gets built on the bench the plugs are just screwed in by hand; the reason being is after installing the engine the plugs are to be pulled again and the engine spun over with the starter to prime the oil system up before its initially started. This avoids a ''dry'' start and premature engine damage. hope this helps

Thanks, I'll check it out. I think it may just be an exhaust leak. I hope its just a loose sparkplug though lol. Would be much easier to fix.
