Okiki Olufokunbi Posted February 4, 2014 Share Posted February 4, 2014 Hello,I am getting a stream of water and some steam coming out of the valve cover breather pipe on my CH613 with E7 Vmac non-etec engine. I am also looking coolant/water out of the reservoir. The vehicle has not overheated.The intensity increases as I rev the engine.I will appreciate any help as to what may be causing this issue.Thank youOO Quote Link to comment https://www.bigmacktrucks.com/topic/34533-e7-engine-valve-cover-breather-venting-steam-and-water/ Share on other sites More sharing options...

Okiki Olufokunbi Posted February 12, 2014 Author Share Posted February 12, 2014 Guys, thanks for the response, but I turned it off prior to asking the question. The heads have been pulled, and they are not leaking or cracked. The water out of the breather is quite cold, so I do not know if this means anything or not. The oil in the sump does not appear to be contaminated. I will appreciate any help as to what may be causing this issue.

turckster Posted February 12, 2014 Share Posted February 12, 2014 Do the valve covers and/or oil fill cap have a grey sludge like substance on them? If so you have a coolant leak into the engine. Usual culprit is leaking past liners because of an eroded counter bore ledge or leaking core hole plugs in the heads. Before you removed the heads you should have pressured the cooling system, removed the oil pan and valve covers to find out where the coolant was coming from.I'd still pull the oil pan and look for signs of leaking liners. Good luck Quote Link to comment https://www.bigmacktrucks.com/topic/34533-e7-engine-valve-cover-breather-venting-steam-and-water/#findComment-232090 Share on other sites More sharing options...
Okiki Olufokunbi Posted February 14, 2014 Author Share Posted February 14, 2014 The culprit appears to be leaking core hole plugs in one of the cylinder heads. The two heads were removed, the oil was changed, and the heads were re-installed. Upon starting the engine, one of the heads had some water contamination. The other one looked normal.Thanks Turckster..OO Quote Link to comment https://www.bigmacktrucks.com/topic/34533-e7-engine-valve-cover-breather-venting-steam-and-water/#findComment-232486 Share on other sites More sharing options...
