Troll Hunter Posted November 7, 2015 Share Posted November 7, 2015 Sorry all, but I'm having a blonde, senile, or just plain stupid moment, and I haven't yet had a bevvy. Perhaps that's the problem. I was preparing to fit new valve oil seals on my installed engine and was about to remove the rocker shaft when this 'orrible thought came to me. Once the shaft is off, how do I know when each piston is at TDC? Should I remove the heater plugs so that I can get some idea through the vacant holes? Please can somebody not yet suffering from mental decay point me in the right direction. Please don't give me clues, I'd have to think about the answer. Just give it to me straight. Many thanks, in advance. Mike Quote Link to comment Share on other sites More sharing options...
cackshifter Posted November 7, 2015 Share Posted November 7, 2015 The timing mark on the flywheel give you no.1 tdc. If you put a mark on the crank pulley it's easier to know after approximately. Fix 1 an 4, turn 180 and do 2 and 3. Without a rocker shaft all valves are closed, who is firing doesnt matter. Just staryt with the timing mark, as if changing the cambelt.

Troll Hunter Posted November 7, 2015 Author Share Posted November 7, 2015 As I said, my engine is installed, so I can't access the flywheel, and I'm loathe to start opening the front timing belt chest. I'm hoping that somebody will confirm that there is an alternative method of determining TDC. Mike Quote Link to comment Share on other sites More sharing options...
elbekko Posted November 7, 2015 Share Posted November 7, 2015 You can see the mark through the wading plug hole in the bellhousing. Quote Link to comment Share on other sites More sharing options...
