I added an 8 pass cooler with a fan and oil filter on my top cage . I added about 1/2 qt of oil because of the added volume of the oil system. Now at idle (after warming up) my rear pully is dripping oil. I bypassed the filter and still dripping. did I add too much? Should I not add any? I previously ran an 8 pass with no fan and no filter and had no problems.

do you have a sand seal on your pulley or a stock style?

It is an after market degree pully that was on it when I bought the buggy. So I'm not sure. I road it before putting the cooler on and it never leaked. I just wondered if the extra 1/2 qt of oil maybe was too much. but I didnt want to run it low with the extra volume of the cooler.

You should add more oil.. I run an extra Quart in my buggy.. However, I had to replace my aftermarket timing pulley with a sand sealed pully to get mine to stop leaking.

As for the correct amount of oil, I run my engine for a few minutes, shut down the engine and then quickly check the oil level. If my buggy sits for a few hours, the stick will show too much oil but after running for a few minutes, it will show the correct amount of oil.

Sounds like the sand seal pulley is my answer. Thanks everybody.

OK, I bought the new sand seal pulley. I Went to install it and realized it already has one. Snugged the oil pump cover bolts thinking they were the problem. We road a little yesterday and its still leaking, not bad but a hassel knowing I gotta check the oil all the time. Looks like the pulley. I'm going to go ahead and install the new seal and pulley.

Yeah i would go ahead and replace the seal and pulley, that should solve your problem.

I check mine with motor running and keep it between the two marks. Run two motors without sand seal and no drips.

Also make sure crank case breather isnt getting clogged . The pulley is first place it will push it out if pressure starts to builds up .

New sand seal pulley and seal did the trick. Leaks gone. Are some of the pulleys cut deeper??? My belt is a little looser and I'm running no shims.

you got to have 8 - 10 shims or it wont tighten up, they can be in the middle, outside, or a mixture to get the right tension

I realize that, all my shims are on the outside, bringing the two puuley halves closer together which should tighten the belt to its max. Thats the way it was on my old pulley. But the new pulley must be cut deeper because the belt is a little more loose than before.
