I'm hoping someone can snap a picture of the distributor with it's cap off - to show where the Rotor is pointing while the engine is actually timed to 27 degrees (the normal factory timing over all the 914 typeIV engines, I believe).
No adjustments would be needed on your end of course - BUT to make the picture usable it would require the photographer to rotate his/her engine to the initial timing "0" degree mark on the compression stroke with the engine off. (your car stays timed at 27 of course) Why do I need this? - because I'd like to get the rotor in the ball-park before my assistant (w/ very limited experience) tries to maintain 3500rpm with my somewhat sticky throttle (to address soon). So, may be kind of a hassle but I'd think it could also help others trying to time their engines for the first time too. We know what the rotor looks like at TDC, but there are no pictures available like what I'm asking for (I looked but couldn't find). I'd appreciate it if someone could help please! ps - if posting the pic is an issue, I can provide my phone# so you can text it to me and I'll post it. LMK |

QUOTE(ClayPerrine @ Apr 26 2025, 12:10 AM)  Actually, that is somewhat incorrect. Yes, the engine will run with the rotor pointed to any distributor tower. However, on a VW Type IV distributor, the #3 point cam lobe is retarded about 3 degrees from the other three. That is to drop the temperature on the hottest running cylinder. So you have to install the distributor drive correctly or the #3 cylinder will run hot. This only applies to factory distributors. I don't know about aftermarket distributors. In 40+ years this is the FIRST time I've heard about a single cylinder being timed differently than others... I was 100% in agreement with @fixer34 . Folks get so worked up on clocking when it really doesn't matter. Clay's note is the kicker... Ninja golden rule: " There are always exceptions". With a stock distributor clocking is important on a T4! Thanks Clay! Little stuff like that make this the best forum... This is EASY to test/verify. Time it up on #1 and then move inductive pickup to #3. |
