Mine can, but to do it right, you need to do the oil pan too. It too is removable without pulling the motor. h

I thought my oil pan was leaking up front and it is pooling like yours. After checking everything over it looks like it's my power steering pump and the fluid was low.

Yes.

I'm in the middle of doing this right now myself. You DO need to pull the oil pan also. The timing chain cover has a lip on the bottom that interlocks with the front edge of the oil pan.

I traded my CJ for this car and I am not yet used to only being able to squeeze my head underneath instead of rolling under on my creeper! I did notice that the oil is spraying a lot less, (if at all) after I fixed the PCV issue. It was disconnected and hanging. There is just so much oil underneath that I can't be sure. I am going to have it put on a lift tomorrow to finally get to the bottom of the issue. Thank you everyone for the input!

Although...I do have an unrelated question...... The car sat for 2 years with 1/4 tank of gas. Due to where the car was at the time, draining the tank was not an option. So, injector cleaner, sea foam, and octane boost were added along with 1/2 tank new gas. I have changed the filter, but what else would you recommend I swap out? Plugs, distributor and rotor, HEI?

Thanks!
Shawn

That stabilizer you're referring to could be the Rack for the steering. Those could be power steering lines leaking. They would also leak more at higher rpm's. Good luck.

Going to revive an old thread here. When I removed the torsional dampener (harmonic balancer) whatever you may call it, I ruined the threads on my camshaft. Now I can't install my pulley, or my balancer....... Anyone know what size tap that would require?

Thanks from a newb...

Nostrash - I chased a small oil leak on one of my other rides for over year - like to have driven me nuts. Got tired of looking so finally sprang for an oil leak detection kit - it cost about forty bucks on Amazon. It consists of a bluish led flashlight and six bottles of dye and some directions. It is by no means a professional piece but for an occasional use it works just fine. The pro systems seem to have a much larger light but this "el-cheapo" one works ok by me.

Initially, I just dumped a full bottle of dye into the cam cover, fired the engine and turned on the light, - and found nothing at all. Decided it might be time to read the directions and subsequently discovered the fluorescent dye will glow better when using fresh oil. So, changed the oil and as the directions said, added only one-half bottle of dye to the oil. It worked - found the leak in no time flat! The dye is a yellowish color which glows bright orange when exposed to the blue led flashlight. Best money I ever spent and still have over four bottles of dye left but the dye is available separately as needed. The directions say it can be used for engine, transmission, cooling system and air conditioning too. Dunno for sure but it might be best to start with fresh fluids in these other systems as well.

Spring for one of these kits - makes life a lot easier and you'll have more time to enjoy a beer or two after you find your leak. Beer always taste a lot better when you triumph! LOL!

Incidentally, the oil droppings on the paper towel in your pics seem to be a little pinkish to me. That indicates transmission or power steering and not engine oil. Since it is on the passenger side, my guess it that it is ATF.

Anyway, just what I did -

Good Luck.

EDIT: Oops - just noticed there was a second page for this post - me bad. Sorry folks -

Jake
