What is the exact location of the timing marks on a 1986 Yugo GV? I can't find it on the oil pump pulley.

I have a 1991 Yugo GV that I bought for the chassis, it is being converted to electric. I believe this motor and prehaps other items may fit the Fiat X1/9 also.

SOURCE: timing marks

this is a complex fix. if the timing belt is off, you will have to align both of the cams (V6??) to their respective notches on the back plate that protects the belt. You must also align the crank shaft to TDC, top dead center. Put the belt on (with tensioner off) then put tensioner on and release allen key. turn the engine by hand or using the starter two full rotations, the notches on the tops of the cam pulleys should be perfectly alligned with the notches on the back plate. if not, you missed a notch in the wrong spot and have to try again.

i've done this twice, once on a lexus es250 v6, and again on my 94 camry, its one of the hardest things i've ever done when repairing cars. be patient, have a friend help, don't get frustrated. if you really cant get it, have a mechanic come to your house and drop him a few bills to help you. you'll be glad you did

SOURCE: need to set timing marks on a 1986 plymouth reliant

To save some time I'll guess and say it's the SOHC.
1). Make sure the #1 piston is on the compression stroke @ Top Dead Center. You can find the compression stroke by pulling the #1 spark plug and putting your finger over the hole, while a friend bumps the engine. When you feel air come out of the plug hole, your on the compression stroke. Then point the rotor to #1 on the cap, by turning the crankshaft by hand. Then do the timing marks.........
2). The camshaft gear: There should be four large holes and one small hole, the small hole should face perfectly straight up. You can use 2 of the larger holes, one on the left and one on the right from the camshaft attaching bolt, to help line it up correctly. By looking through them, horizontally line them up with the head.
3). The crankshaft gear and the intermediate shaft gear should have a dimple on one of their teeth. Face them to each other.
4). Make sure nothing moves, when installing the belt.
5). Fire it up, before you put everything back together. When it fires, let it run for about 30 seconds to let the belt align itself. Then check all your marks again, to make sure nothing moved.
6). Put it back together.
7). I sincerely hope that this information helped you to get r dun. Best wishes and God Bless.

SOURCE: 1986 jetta oil pump location and replacement/knock sensor

oil pump is in the oil pan and if you have no or low oil pressure replace pump before doing anything with knock sensor. knock sensor is more or less a microphone and listens for spark knock but will set codes for any knocking or tapping noise which is commonly heard if oil pump is malfunctioning

THe timing of the oil pump is irrelevent as no matter where it is timed as long as it is pumping oil. you must have a leak from a cam or crank seal or maybe the oil pressure sender. hope this helps. regards Ben.
