As some of you know, #1 and #2 cylinders of my back-up race engine are pretty low on compression (110 and 115 psi) compared to #3 and #4 (145 and 150 psi). I squirted a bit of oil in the cylinders and the compression only gained a few psi.
So, I have a little break in the racing and I decided to pull the heads and do whatever valve work is required. Here are some pics. Looks like the intake valves hit the pistons a little bit, maybe on a over-rev during a downshift. Cyl #1 and #2 Attached image(s) |

Wow this should win the best thread of the week award. Actually some really good real life stuff about fixing a motor. and the "hey I'll even throw in some parts to help with cost stuff" I love it. This is why I hang out here.
well and the occasional boob shot. (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif) The intake port is kinda funny looking. DIY with a touch of "never done it before" What does the exhaust look like? same thing? ALWAYS use caution when porting heads. It's easy to take too much. Smaller passage promotes more velocity. at least that what I believe. |
