I picked up a complete 2.0+ engine today, came with all sheetmetal, alt, starter, fan, twin Italian 40 IDF carbs, etc. The seller got it second hand from a disabled N. Texas guy who'd crashed his 'real nice orange 914 with spoilers'...he remembered that it was built in Ft. Worth TX and said that it was over-bored but could not remember the details - said "it was built to a 2 point something" (IMG:style_emoticons/default/confused24.gif) (IMG:style_emoticons/default/headbang.gif) . Said the PO seemed honest and assured him that it was a fast, strong engine. It has a GA engine number. He was asking $700 for everything and I figured at the very least it was a descent price for a 2.0L + dual 40IDF webbers, so I bought it. I've asked some locals if they knew anything about it and none did.
Whats the general concensus, just do a leak down test, compression test and use it if within spec... or break it down and start taking measurement? |

Do you have to compensate for removing the head sealing ring with shim rings at the base of the cylinder? I'd assume if we could locate shims for the case side, that equals what was already there + the thickness of the seal rings - then replacing the shims would be ideal for maintaining the compression ration. However, like was mentioned those seal rings are really thin, so I'm not sure if it's possible. I plan to lap the head/cylinders, it's common procedure when deleting the seal rings but another questions I've been wondering.. is there any such lapping done at the case side with cylinders, shims, case ? Also, have I read that there's a paper gasket that gets eliminated too? The registers were really hard to get clean and flat on my engine. When I first checked the deck height it was different on every cylinder. There was paper and glue residue from the factory paper gasket on the registers. Once I got the registers clean the deck height was close to the same on all 4 cylinders. I had my cylinders bored to 96mm and used flat top KB pistons. If I remember correctly I had to ad a .030 shim to get the compression ratio right. http://vwparts.aircooled.net/Cylinder-Base...-base-shims.htm |
