Also makes me wonder, if the 7m needs a PVC system hooked up and working, why I see so many pics of people's engines with the PVC ports just hooked together...

Makes sense. I'm going to pull off timing cover off to see what is leaking, probably replace all the seals i can, as well as fab up a new intake pipe so I can hook the PVC system back up.

They are hooked to a filter, venting them.

So that hole is just for if oil is leaking from somewhere in the timing case so that it doesn't build up?

I've searched for an answer but can't find an answer. I've been having problems with my 7m since I've bolted on my new turbo. I have a pretty bad oil leak, it is coming from a hole in the front of my engine, just above the pan gasket, behind the crank pulley. What is this hold for, and what...

Bump

-10 an. No sharp bends, all down hill. No obstructions.

I've got a hy35 I installed a little bit ago. It was leaking oil bad out of the turbine seal. I replaced the piston type turbine oil seal and it better but still wants to smoke quite a lot. The whole turbo was rebuilt less than 100 miles ago. I have a .065 oil restrictor. And it is still...

So I put new plugs in, gapped to .025 an no more spitting. I only drove it for a short distance, but it seems when I give it full throttle and it spools up, didn't see to what psi, it runs good and pulls hard, and them all of the sudden, falls on its face. Then I let off the throttle, and it is...

Thanks for everyone's suggestions. I'll be at the shop tomorrow and look at the plugs. What gap should I run them at?

Most psi I've seen is 20, it starts spitting at about 13-15. I've got a Walbro pump, hks ssqv, intercooler and hard pipes. Full 3 in exhaust. No codes. As far as the Maft pro, I haven't tuned much. I was using it before I installed this turbo and injectors, so I just left everything set as it was

Just got done building my car, and got the boost leaks fixed. And now it is spitting under boost. I have a couple ideas on what it might be, but not sure where to start, and don't want to throw more money at it. It has a holder hy35, and 560cc injectors, running Maft pro in speed density. I...

I just put an oil restrictor in, and it is still leaking oil. Also when I shut the car off, I can hear a hissing of pressure coming out exhaust housing? Is the seal blown? Does the whole thing need rebuilt or can I just put a new seal in?

-4 feed, -10 drain. Stock gauge usually reads below 40psi.

Is there a specific size I need?

I was saying, if I had a restriction, or block in the return line. And this is what was causing oil to come out the exhaust, would I just need to fix the restriction and all I well, or is there a seal blown in the turbo. If it is just simply getting too much oil, would putting a restrictor on...

I need some help with this. I just installed a newly rebuilt hy35 holset and it is leaking oil out of the exhaust housing. I need to know if a restriction in the return like would cause this, and is so, would just fixing the return line solve the problem, or woul I need to repair the turbo? If...

Would putting a restrictor in possibly solve the problem? Or would I need restrictor and to fix something inside the turbo?

I just installed a holset hy35w. Was rebuild less than 100 miles ago. Noticed oil leaking from under the car. Traced it from the exhaust side of the turbo. Pulled the downpipe off. Started the car, quite a bit of oil is coming out from the turbine. What would cause this, and how do I fix it? Thanks

It doesn't smoke much at all. I've only driven it like 15 miles. Drain is -10, feed is -4
