Newdesertfoxowner Posted November 19, 2018 Share Posted November 19, 2018 I'm looking at this oil leak I have. Nothing major but it leaves a spot on the driveway and cruds up my engine bay (rust protection right?). The leak seems to be coming from behind the crank pulley and dripping down the front. It does leave some residue on the underside of the air filter housing. Anyone have any tips, tricks, videos, diagrams or such before I dive into this?

Crazyeights Posted November 19, 2018 Share Posted November 19, 2018 In addition to the front seal you are going to want to pull the oil pump and replace the oring seals too. Be careful not to break the pump when pulling it off. Twist it using the filter as a handle don't pull real hard or you'll crack it. Quote Link to comment Share on other sites More sharing options...
silverhelme Posted November 19, 2018 Share Posted November 19, 2018 While you have the crank pulley off check it for cracks. I've had two that leaked because of a crack in the pulley. Quote Link to comment Share on other sites More sharing options...
Newdesertfoxowner Posted November 19, 2018 Author Share Posted November 19, 2018 Do I need to pull the oil pump to get to the crank seal? It didn't look like it. Are the oil pump seals a necessity as preventative maintenance? I'm new to these engines so anything you can tell me is appreciated. Quote Link to comment Share on other sites More sharing options...

The thing is, once you start taking things apart its silly to only replace one seal. Might as well do all the front seals including the oil pump. Depending on the engine mileage and the last time it was resealed, you may want to remove the engine and reseal the whole thing. It's much easier to do out of the vehicle than in. And you won't have to come back and take everything apart again for the next small leak. If one is leaking the rest are not far behind......

Newdesertfoxowner Posted November 19, 2018 Author Share Posted November 19, 2018 I get what you're saying. I'd love to have the ability to do all that. But winter is coming and I have only a driveway. Between that and a lack of serious funding I'll just stick with my current leak. This is a secondary vehicle so it's not super important to get done right away. Quote Link to comment Share on other sites More sharing options...
DaveT Posted November 20, 2018 Share Posted November 20, 2018 That situation it makes sense. Just beware, the crank seal may not be the only leak. Quote Link to comment Share on other sites More sharing options...
el_freddo Posted November 20, 2018 Share Posted November 20, 2018 I’ve done it on mine. The crank seal was SOOOO old and crusty that a bit broke off and it leaked over a certain rev. I limped it home at 80kmph hoping the oil light didn’t come on. That was a very nervous 28km. I did as above - crank seal and oil pump reseal at the same time.
