Got inspired to restore my vintage gaspump a 1958 Ljungmans Star 87. Electricmotor, pump, wires etc was removed by me earlier so just the rest of the stuff needed to be taken apart and cleaned and highpressure washed. Lots of old diesel everywhere. Going to be a BP (British Petroleum) again like it was new 1958.
Started to disassembly the VW Baywindow Highroof engine this weekend. A stock Type 4 1800cc AP case (no hydraulic lifters) and dual Solex carbs. Going to be rebuild from ground up and get some extra performance parts for even more torque! Plan is to resurface the heads, 96mm Porsche 914 cylinders, better carb setup and a better flowing exhaust system. Probably going to keep the stock camshaft ratio, because it gives maximum torque already around 2200 RPM, wich is perfect for a heavy bus and hills.
The engine was already unbolted when I got the bus and I did not know anything about it, more than it was a AP 1800cc VW type 4. I saw it was cleaned a little bit and the cylinders looked to have new paint on them. So somebody have started to restore it was my guess. But I saw that the lower cylinderhead cooling thins was missing, so I got a little suspicious about how good restored it really was going to be when important parts like that not was installed back. Hmm!
Here is some new pics…
Teardown started, cylinderheads is off! Something have happend in cylinder nr 1 at some point. It had small marks and dings on the combustionchamber and on top of the piston. Nothing to serious tho. Maybe a washer or parts of a valveseat? One of the valves was new too. Funny thing is that the piston that had marks was now installed in cylinder nr 2. Not a good thing to mix them up on old used cylinders. But doesn’t matter now since I will replace them with all brand new 96mm cylinders and pistons.
The good thing is that the cylinderheads are the ones with partnumber ending with an “S”. And have the biggest valves VW ever put in any bus! Intake 41mm and exhaust 34mm. Bingo! Only Porsche 914 had bigger, and they also had a different angle on the sparkplugs for better performance/combustion. Heads will get rid of the headgaskets, resurfaced 0,5-1mm, new valve guides, new machined valveseats in a better material (Type 4 engines are famous for dropped valveseats) and new valves and new springs etc.
When I pulled of the nr 4 cylinder I found a rag inside the case(!) Somebody probably forgot it there. Ig the engine had been started up it would not run for a long time thats for sure! It was now confirmed that a total crackhead had restored my engine before.
Camshaft totally shot! And nr 1 cambearing was worn down to the copper. Camshafts are almost never in good shape on the Type 4 engines, even worse on the later ones with hydrauliclifters. Highpressure and not the best design on the cam/followers are the main reason for this.

Have not got very much done lately. As my first son (1 year old) takes most of the time now. So that more important at the moment. But Im trying to push forward on the bus too, couple of hours after work and on weekends etc. Soon have all doors and lids in primer and then it all just needs a easy sanding and then its time for a paintjob! Have also sandblasted the fueltank cover and bellypan and got them painted and ready too. Hope to start rebuild of the 1800cc Type 4 engine in begining of February also!
More to come, but thats it for now, here is some pics…
Topcoat in VW L20a Marino Yellow with 2K polypaint with elastic characteristics. So the stones wont chip the paint. The gloss on the elastic is a little less, but this panel is under the car and you normaly never see it anyway.

When winter comes knocking on the door, its nice to watch videos from the bus summer! Take me back…
Slow with updates? Thats because I have been busy doing bodywork on the Highroof bus. A very boring, dusty and time consuming work. But now its in surffacer/filler/primer and ready for more sanding again, and hopefully thats it before paint. Paint for roof (white) and body (VW L20a Marino yellow) is bought. Still have all the doors and lids to do also! Got some new parts too, new lids for electric 240v hook up and fresh watertank filler with lock. A Vitrifrigio C60 fridge in stainless will chill the drinks and food nicely, its 60 liters and 10,5 liter is freezer. Danfoss compressor of course!
Sometimes you must work on new modern/boring cars, but now the dailydriver is ready for the winter! And a MAINDRIVE STICKER in the backwindow…
