HS 2.8 L Problem

Hi Guys, I have a 2.8 that I just installed in my Series 3 Stage 1. I have just a bit over 400 miles on it when I noticed a oil leak (more than a few drips). It appears to be coming out of a threaded hole between the front of the oil pan and behind the crank pulley. I believe this hole to be a drain for the timing belt cover. Thou it is threaded I assume it is still a drain. Is this true? Could the problem be a bad front Main Seal? If so, any one know if they are a common seal that can be sourced at the local auto parts store? ( ie.Timmken) How about the replacement process, is opening up the timing cover a straight forward project? Unfortunately the service manual that I down loaded hasnít been much help. Thanks in advance for any help!

can you post a pic of the hole (well lit) and I'll take a look at mine to confirm you are not missing a bolt.

This is the timing cover breather as per M&D. I bought a plug for this, which is needed when wading.

Are you sure the oil is coming out from inside? Sometimes there could be oil running by this hole, leaking from somewhere else, and climbing up this hole. Maybe splashed from leaking transmission oil cooler lines, or from the the seal between the oil sump/crank case interface.

Unfortunately my daughter has the camera and is with her friend on vacation. The hole is about a half inch in diameter and is right between the front of the oil pan and the back of the crank pulley on the bottom of the timing belt cover. Pretty easily seen from below looking up! Any help would be greatly appreciated!

The oil is defiantly coming from the hole. I put a plug in and drove a few miles then removed the plug and had about a quarter cup of oil drain out!

That is a good amount of oil. I can see your concern. I am the cautious type, and would not run the engine and contact the seller ASAP.

agreed. that much oil means a bad seal somewhere in there. probably main bearing.

A 300 tdi workshop manual will walk you through this repair. I think the seal is the same as well. When you get the seal out you can give me a call and I will help you source one Stateside. I'll PM you a phone #
