So I decided to clean up my original engine while I run the car with a modified scat engine.
When I drained the oil I found these....two small pieces and the nut.....(dime for size). So I started to tear down the top end and found one cylinder that looked not so good. The others are the same as the right side. went down further and removed the pistons and am now cleaning them all up. Everything looks ok. I really don’t want to split the case or go any further and from what I see inside all look good. So two questions.... 1) any thought on why this cylinder isn’t firing right ? 2) can I use something like gasoline or similar to flush and clean out the inside of the case with the crank and oil pump etc still attached? 3) any reason why I can’t use all the old parts ? 4) any thought on the nut? Thanks.... |

@ simonjb
Don't take this the wrong way, I have no idea about your background and experience with engine rebuilds. But, based on your questions, I would suggest a few things: 1) Read the factory manuals. Get familiar with this engine, its parts, and the components. http://p914-6info.net/Manuals.htm 2) buy the CD from Jake Raby on how to rebuild type 4 VW engines. They are different than than typical VW type 1 engine. It appears to me from your heads and pistons that you have a 2.0L which is just another more unique variant of the typical type 4 than you might othewise find in 914's (1.7L/1.8L) or a VW bus. Sample of video below. The cost of the CD will be saved x10 in mistakes later. Plus it's entertaining to see Jake so young! We were all much younger back then! (IMG:style_emoticons/default/biggrin.gif) https://www.youtube.com/watch?v=-OOwrsOmXJc 3) Before you go buy a cam you need to know what you want to do with the engine. Will it be stock Fuel Injection (FI) or will you be running carbs? The cam selection will depend on the answer. I can't see much from the photo of the stock cam but from what little I can see, it almost appears that that cam doesn't even have much wear on it. Can you post a photo of just the cam lobes at the most narrow end (in side view)? That is where the typical wear occurs. You typically get a noticeable U shaped trough at the center of the lobe where the two lifters share the same portion of the cam lobe. As a community, the members here are awesome & are here to help, but, if you're not already familiar with Porsche 914's and Type 4 engines #1 and #2 are priceless resources. |
