cr83 Posted July 7, 2014 Report Share Posted July 7, 2014 Does anyone know if an L16 timing cover will fit an L18 engine? I assume mine is cracked because I have oil in the antifreeze, and I have an L16 engine for parts, thanks Quote Link to comment
dr.feltersnatch Posted July 7, 2014 Report Share Posted July 7, 2014 Yes it will. L16 and l18 are interchangeable l20 is not. Quote Link to comment
cr83 Posted July 7, 2014 Author Report Share Posted July 7, 2014 That's what I wanted to hear, thanks, is that a common problem? Quote Link to comment
CrazyHawaiian760 Posted July 7, 2014 Report Share Posted July 7, 2014 A lot of different things could be cracked ...What make's you think the front cover?? Quote Link to comment
banzai510(hainz) Posted July 7, 2014 Report Share Posted July 7, 2014 What you dont want to hear is most likely is the antifreeze will be in the oil if the front cover is bad behind the water pump area. when it pressurizes then water gets in oil pan!!!!!!!!!!! this happens from cavitation (lack of good antifreeze) must be changed out every 3/5 yrs esp with alum heads and covers. I would fush it out first a couple times then look. Might be nothing Quote Link to comment

If oily sheen on coolant in the rad, this could indicate a failing head gasket. Compression and combustion gasses might be forcing their way into the coolant. Does your rad need topping up every few days? Does it over heat? Quote Link to comment
JNHEscher Posted July 7, 2014 Report Share Posted July 7, 2014 The gasket between the block and cover could be leaking. If you pull the water pump off, you'll see the water passage. Looked like a place for trouble when I did my timing chain. If the gasket leaks, the water runs right down into the pan. Quote Link to comment
cr83 Posted July 8, 2014 Author Report Share Posted July 8, 2014 Doesn't burn any coolant, and no coolant in the oil, only oil in the coolant, the truck has done this for years and was parked, i recently read a post that someone else had this problem, and that they found a crack in the timing cover, i am going to rip it apart soon and check it out, the engine runs excellent otherwise. I assume it would leak into the coolant because the oil pressure is around 40 psi and the coolant pressure never exceeds 16 psi. Quote Link to comment
