1995 Long crank time when hot

[Articcatzl440]

Well my 95 has just started doing this, when its cold it start perfectly, but once the truck is hot it takes like 10 to 15 seconds of cranking before it will start. The truck has brand new injectors from rosewood stage 1.5 a new hpop from terminator engineering all less than 3 or 4 months old about 7000 miles. The truck always starts just wondering why its starting to crank longer when warm. I was also given royal purple 15w40 for my last oil change and i noticed i was low about 3 quarts changed it back to straight rotella and now it hasn't used any oil is it just the super thin oil stuck in my hpop system that needs to get worked out or is the ipr or icp going or is it my cam sensor going. Any ideas would be greatly appreciated.

Thanks
Cole

A lot of times it is the o-rings on the IPR letting warm (thinner) oil bypass. Either that or you have other HP oil internal leaks (one wouldn't think so with the new stuff). Cheers!
