Super helpful thank you. I have the engine out of my 78 on the stand and I want to tear down that far to clean up some oil leaks and see if I have any other issues. Much appreciated!
Thanks Mike. Type 4 not my forte but it was nice to get into one while I had it out. I have so much to learn that I forget what I’ve already learned. Lots of fun though, good luck with the 78, thats a strong beefy engine!
Hey there thank you for the info ..well documented and explained...be buying a type 4 soon and gona boost it..we will see!200HP ? ill be happy with that on all stock internals...goal is to push it 200..then 225..and so on till she blows then well reverse engieneer the ffailure see where it can be improved
Is there any kind of gasket or sealant between the cylinder head and cylinders themselves? I bought a gasket kit, just wondering what the thin metal rings were used for.
Hey Justin, there is no sealant of any sort where the cylinder and head meets. The best bet there seems to be a light lapping job by putting some lapping compound in that area and spinning the cylinder around by hand, in order to mate those surfaces together (be sure to clean the compound off when done). The metal rings were intended to be cylinder to head gaskets, but it seems that their use is controversial, and supposedly VW eventually quit installing those…but I can’t confirm that. I can say however, that those metal ring gaskets aren’t necessary to achieve a good seal. Hope it helps and best of luck with your endeavor.
@@bomberobus Thanks for writing back, your info was very helpful. I watched your video of you cleaning the Rooster van's engine with a toothbrush. I bought a 73' hightop adventure wagon back in 1999 that was sitting since 1986. Got it running in 99'. Dropped the engine out but the mice have gotten to it, so now I'm cleaning with a toothebrush. Watching you pull the heads has given me confidence to do the same. Thanks.
Yeah I’ve finally gathered enough info to wrap my mind around the type 4 to 1 deal, but I was also hoping to swap the 091 tranny into the ‘70 Bus too, which seems more of a problem. Also the price of the conversion might keep just doing what I already do and build a bigger Type 1 for it.

Learned something new... Thank You!
As do I, all the time. They’re “simple” yet complicated haha.

That is an exciting plan and sounds like a lot of fun! The type 4 parts I saw looked pretty tough so I’m curious to the outcome. Stay safe and enjoy.
Good info. 👍

Haha yes the good old toothbrush. VW guys use what we have and make it happen. Go for it🤙🏼
What size engine is it?
That’s a 2 Liter out of a ‘77 Bus. I still hope to stuff it into a ‘70 Bus one day if I can ever figure that out
If the 70 bus is an type 1 configuration you have to convert the type 4 to the type 1 configuration.

Where did you get the bell housing to build the bench start system for the bus?
It belongs to one of my Vdub buddies. I couldn’t have done it without him!
