Hi Guys, It's time to do some routine off season maintenance on the 914. The car has a 2.2s spec motor. My question is, how do -6 owners adjust the ignition timing prior to a valve adjustment? It looks damn near impossible to get a timing light reading. I know cutting into the firewall is an option for ease of access but I'm not willing to get the cutoff wheel out yet. Does everyone drop the motor and tune at a shop that has a running motor stand? I'd just like to double check the ignition before setting the valves. Thanks in advance.

I actually thought about the mirror. Then I envisioned myself either dropping the mirror into the rotating motor or getting the timing light caught up in the fan pulley assembly. Also thought about building a running motor stand. But that seems like a lot of work just to check the timing. Unfortunately not a real 6, so probably no marks on the flywheel unless the previous owner and engine builder were thinking ahead. I'll have to check on that.
Ok fixer, fill me in on the modified 930 valve covers. I opted for heater delete headers for the moment. I currently have the stock exhaust covers on with no leaks but was thinking of changing to the lower 930's. What am I in for? Thanks. |

There have been some other answers on here, but basically the 'turbo' covers with the ribs/fins will hit the suspension mounts and won't clear the studs when trying to remove them. Some people have swapped out the upper studs for bolts, others have milled all the ribs down. Doing the entire cover is not necessary, there is only a section around 2 of the stud holes that needs to be done (have pictures of what I did around somewhere...). Just trying to head off a surprise for you. My original covers warped so bad that oil was leaking almost constantly. Bought a set of the turbo covers 4-5 years ago and aside from the 'surprise' trying to install them, they have been fine. Looks pretty cool down there although no one sees them... |
