Not sure this thread would qualify for the "Vintage Speed" Category but I like reading about the 36Horse engines and things people do with them. I had the 56 356A Engine that originally came in my "A" apart, there were a lot of improvements over the Case Castings plus they were Aluminum. But I think one could drop the 356A crankshaft and Flywheel straight into a 36 horse vw engine. Not sure what rods, the 356A Pistons used 22mm wrist pins but I think the 356A rods were 36 Horse size (What 50mm) at the crank. Maybe not so simple found this Crankshaft Questions VW 36hp with a Porsche vs 356 crank Rods Journals are 53mm! I see now there are AA Performance 36 Horse rods available with the option of 20 or 22mm wrist pins.

Well, this theory I came up with does not prove out. I thought If I tested start up starting from different positions that I could find which cylinder is causing the smoke. It smoked the first two times I tested it both test set 90' btdc #3 but that was it, I could not reproduce any smoke testing all of the cylinders in the same manner. Here is a Video: Smoke Test I think what I will try is, see what position the engine just happens to be in before starting and see if that effects when it smokes that way I can give it overnight between test.
The other day this thing was smoking a bunch of oil smoke almost every start. |
Update The Engine now has 3500 miles on it in the car. The smoking problem persist intermittently only on start up. I changed the plugs going from Bosch W9's to W7's but didn't see any sign of oil deposits on the W9 plugs.

Hi Dan.
This is old guy up north ya.. remember rag joint/steering coupler, plus you drove Bus, I was suppose drive yours. But that got cut short deal.
ya know late summer of 2019. I said I'd back in 3 weeks tops, while replacing that 1600 cc engine, with the 2176 buggy motor, Right? lol.
3 years later the 2176 is a 2080. Still not usable. which is why I really need to talk with you.

The Engine is still in the 1960 VW Beetle and is running fine, running Mini Cooper Spark Plugs Bosch FGR7DQP+ as they are easier to change and they are Bosch Plus +4 plugs and the engine is better on take off. The Smoking Problem seems to be clearing up over time it now has 7071 miles on it and only smokes a little occasionally on Cold Starts after it was Shutdown Hot and left overnight or longer cool down. Going to switch the motor oil to (Mobll 1) 0-W40 at next oil change and see what happens.
