Perkins HT6.354 oil level
Now I will raise a question, on the HT6.354 engine which I think several members have. I find that if I fill mine to the full mark on the dipstick, the oil does not cover the oil cooler core in the oil pan/tank. In order to cover this I need 3 more quarts raising the level 1.5" above the factory full mark on the dipstick.
The shop manual for this engine calls for 12.6 or 13.8 in one manual depending on "early or late" model. An Operators Manual says 13.8 qts., another Operators Manual says 16.8qts.
A parts manual for very early horizontal engines calls for dipstick #31786429 my dipstick is stamped #31786412 and has max. @ 6" and min.@ 7".
I never thought it was a problem overfilling to cover the cooler core since these horizontal engines use a dry sump lubrication system in which the oil pan is really a tank and the crankshaft can't hit the oil. But now I'm not so sure because my engine seems to have more oil smoke and use a little more oil when overfilled like this.
I am putting this question out in hopes someone can help me answer this question.
