First of all I'm new here and want to say hello. I read some of the post an I know there are guys here who are a lot more knowledgable than I am.
I've got a IH 2500B with a D239 engine and a Bosch VA4 inj pump.
The tractor actually runs decent but has some issue's I'm not really sure how to procede.
In the last few months it has started leaking raw diesel out of the exhaust on cylinders 1 and 4
At first I thought it was either injectors stuck open or lack of compression.
It has also started leaking diesel from the return line in several places
It has also developed a leak at the inj pump where the dist head bolts onto the rest of the pump. This leak will spray out when I first start it and then stop, but it will continue to drip even after the engine is shut down.
It hasn't pumped any diesel into the crankcase.
If anyone has any insight into what the problem might be, I would appreciate your input
