96 e7-427 vmac injection pump oil leak

[dtreid]

Just picked up a 96 mack with the e7-427 vmac motor.

I have a significant oil leak coming from where the econovance bolts up to the engine front cover. 

Can I remove the injection pump/econovance from the engine to put a new gasket on without having the mack timing tool?  Haven't worked on mack engines before.  Thanks

You can but your only guessing what the timing will be.I have be told and think so my self that the timing dont need to be advanced more than 2 drgrees above specs.

just a thought.... If he marks the heads of the pump gear bolts, then puts longer bolts in there place, then loosen the pump and slide it back on a guide bolt in place of the econovance mounting bolt's? maybe with a a flat screwdriver he can sneak some Mack Gray RTV. after a good cleaning with brake clean..  What do you think Glenn??  Jojo

that may work.Also if you go to cummins and buy the timing plug or fork that the 5.9 p pump uses it may be 100 bucks but cheaper than a A/B light.The 5.9 timing tool is a plactic fork that will slide over the pump timing spade and will center the timing spade in the window of the pump.I think the p pump came on the dodge engine first 1990.

Also on the econvance there is a oil drain back hole in the bottom of the block that you dont want to get restricted or closed off.
