Clyinders 5+6 B misfire

[rajinder_1]

I was with the guy from MB yday and he was going to swap the injector over to see if its a faulty injector in 6 causing the misfire.
He did pre warn me that there are orange plastic seals which sometimes snap in the process. we got one side of the injectors off and one of the orange seals got left behind, so he fished that one out with a pick (luckily).

Then we took the other side out and 2 of the damn things got left behind.

What could be worse...... well ill tell you, we couldnt see them to fish them out so not the inlet mainfold has to come off to take the seals out as you cant buy them seperate you have to buy whole injector, AND if they are not there the head has to come off!!!!!!!!!!! mmmmmm 15 hrs labour start to finish they think!!!!!! not good im feeling kind of faint......

Does anyone know if the plastic injector seal can damage anything if left in the engine? as explained earlier they have come off when removing 2 of the injectors. or will they have to be removed???

Right just got update.... got the seals out!!!! by removing the inlet manifold.... no need to take of the head phewww. they have checked and apparently they will take the rocke covers off and the sprigs go and cause misfires on the v6 aswell, so fingers crossed they will find the culprit,

It was the fuel all along, there is sludge in theres which blocked the cat and caused the misfire!!!!!! lesson learned DONT USE BP!!!!!
