1G 7 bolt oil pump cover on a 6 bolt

[AlexGsxCummins]

So i got a motor from a guy that he has yet to start. I checked the timing and it seems like a 7 bolt oil pump cover is on it because it has the timing mark for the crank behind the tensioner. Am I stuck with ordering a new 6 bolt cover?

How do you know it isn't a 7 bolt? Did you check?

 

[AlexGsxCummins]

Theres 6 bolts on the crank

Pictures would help.

There is a procedure for doing a 7 bolt oil pump case on a 6 bolt, requires drilling, cutting, welding etc...

Here you go

That’s a Sonata oil pump which has the crank sensor provision and it bolts on to the 6 bolt block, But for sure, that’s not a 7 bolt oil pump.
The 7 bolt has a curve at the lower section of the case.

Edit - it’s not a Sonata front case, It’s a Mighty Max front case. I just clearing up my mistake for future misleading.

Got it. How do I get the crank timing mark correct? I don't see a mark for it where the stock normally is. Or order new?

 

[miguelmcv]

Your timing mark is this one.

I think you have a mighty max front case.

That's a SOHC pump.

 

[miguelmcv]

Correct.

 

[AlexGsxCummins]

I was thinking the 6 bolt mark was here

 

[miguelmcv]

On a DSM 6 bolt yes it’s there but you don’t have a DSM front case check the post before.

 

[AlexGsxCummins]

So order a correct one?

 

[miguelmcv]

I would still use the case and use a dial gauge to find TDC and make a permanent mark on the case for future timing guide.

 

[ThunderChild]

Or use a 7 bolt timing gear backing plate on it. That should indicate it for the correct side, or at least close to it.
