Vw type 3 engine hot/oil leak?
Hi all,
Sadly I had a small engine fire on my type 3 which was no fault but my own silly mistake was a live and learn moment.
However all back up and running now had to replace rh carb, leads, wiring etc however took it for its first decent drive yesterday it went fine as
before however it did start to splutter losing power then clear it self then same again but idled fine. Got home and the engine everywhere was so hot.
Then I noticed that there was oil bubbling on the rear two bolts on the oil breather stand (pic attached). Can anyone help out with any suggestions to
what could be causing this?
I had to clean out the breather and replace the cap that's all the work that was done in the area.
Any help would be great.
Thank you
bevoracing

Wow. I'm no Type 3 expert but sounds like you got VERY hot. Did you have the cooling air intake bellows on the back of the engine? If not it just
circulates hotter and hotter air through the engine. EVERY piece of tin and rubber on and around a VW engine is absolutely essential. Good luck.

Thanks Tony,
Didn't have the fan bellow as was in the process of ordering one however it ran fine before without.
I'm starting to think that when the fire occurred it melted the cap on the oil breather. So maybe the plastic melted and dried inside and created a
blockage because to have oil seeping out on the pedastal stand nuts says to me something is going horribly wrong down there even though I can feel
back pressure/air coming out the top of the breather

Sadly, if you take it for any "decent drive" without the bellows etc. all fitted securely, the engine will probably be destroyed through
overheating. The oil bubbling out is probably due to "blow-by" from distorted clyinder walls/rings (may be permanent/terminal damage from this), or
serious foaming from very over-heated oil, leading to lubrication failure (may not be serious damage IF you stopped in time). If it didn't actually
seize (stop) you may have "got away with it".
There should be no, or little, air/flow felt at the breather tube at idle; some movemnet may be felt as the engine is revved. If there is a lot of
flow (blow-by) at idle, the enhine may be worn out/broken.
