Not sure on your engine Jim without seeing it.

Its fookin important though, I cooked an engine on the dyno today because of an air lock. (Wasnt me who filled it up and didnt bleed it tho! ). Set the engine up on the dyno, got it running set it to 95nm load and 1800rpm, left it running for 10 whilst I paid a visit to the shithouse, got back to find smoke pissing off of it, head looking a rather goldish colour and the EGT at 632degC. (Max for this engine spec was 400degC). Oops Another one scrapped then

So kids, never underestimate the importance of bleeding your engine propperly!
