I'm having a little problem with this and wanted some opinions before I screw something up . I have searched and saw some have clearance issues with this and some don't.

Anyway, I just recently got a Rollmaster double chain and Melling oil pump and I'm having issues with the cover not fitting right. I replaced the stock oil pump bolts with some smaller headed grade 8 bolts and it seems to fit. I put the cover and gasket on snugged it down and turned it over and couldn't hear anything that would be rubbing. I took the cover off and saw no rub marks either.

I just wanted to find out if anyone has done the same thing and it work out for them or not and any other opinions .

 

Anyone?

 

Id say your fine bud. What oil pump? Sometimes the chain itself comes very close to rubbing the backside of the oil pump housing also.

 

Melling oil pump. The chain is close but it all looks like it will miss

 

It is, trust me.

 

It should be fine as long as the new bolts are of good quality.

 

if your using the spacers with the double roller, ck right where the pump/pickup is, they tend to hit there also-a lot easier to see if the engine is out of the car-using the melling pump with a double row chain will hit several places sometimes-if you dont use a gasket, it will show a little better where it hits

 

The meling pump is actually a bit taller compared to like a SLP Pump, if you are using spacers for the double chain, you will need to grind spots on the timing cover to clearance it. On a SLP pump w double chain you 99% of the time have to clearance cut the timing cover, this is per SLP.
