Oil spraying from dipstick tube

[Andy Hamblin]

Andy,
Check the vent, but I think these engines can lose a lot of oil out of an unsealed dipstick tube regardless. I recently made an "o" ring dipstick mod and my engine is so absolutely bone dry now it is almost weird. Nothing on the garage floor now at all. Previously I assumed that all the drips were from several sources but apparently that wasn't the case here. I've driven 150 miles since the swap with no measurable oil use so I think the loss through the dipstick tube was significant.

That's interesting, thanks. I'll continue to check the vents, but might have to just 'plug it up' as you have done. Can you post a pic or describe your o-ring dipstick mod?

Cheers,
Andy

I'm sure you've checked but it is the dipstick hole the oil's coming from isn't it? The front cover joint is the other suspect and older ones often don't seal that well. It's just that to get a puddle underneath after a couple of minutes at 2k rpm suggests you should be able to see it coming out of the dipstick hole. The plug cap fix cleaned my engine up nicely but it was only ever oil mist it had to deal with, nothing like yours seems to be chucking out.

A good lead Stuart, thanks. Will check it out.
