Remnant Performance Intakes Manifold Questions

[SwagginModifieds]

I'm going to preface this with the fact that Alec and I have both gone over this over FaceTime. It is a singular issue, and is in no way shape or form an issue with remnants quality.

I am having an issue with the remnant PI Plate hitting the water manifold. It can be seen with the orange marking. I had to take quite a bit of material off the PI plate fuel rail to get it to fit, and still only have about 1.5mm of clearance all around(luckily I didn't go through but idk if I'd trust 80psi of fuel not to break through ? regardless we're using port injection through the intake manifold). Alec was kind enough to send another PI Plate to test fit and it was hitting the manifold as well. He also offered a full refund, even though it was modified and pretty much installed, but we declined as I appreciate the build quality and research gone into the product.

My question is, does anyone know of any revisions done to either the oem water manifold or the intake manifold deck on the head? I dont think its an issue with the water manifold though because even with the pi plate clearing, the manifold still sits too low. Client has owned the car since new, and Im the only shop that has worked on it or modified it. I've worked on quite a few mkvs and even more b58s so im not inexperienced but i also dont know everything. Can anyone send a borescope down underneath to show how much clearance they have so I can attempt to replicate it?

The intake manifold sits too low even with the modified PI plate rail & phenolonic spacer, and pulling the oil filter out is gonna require loosening the intake manifold. I have probably 1-2 threads remaining when the oil filter housing hits the Remnant intake manifold. It did however pass a 20 psi smoke test but we plan on pushing quite a bit more then that with this build, so we will see.

It's a gorgeous manifold though ?.

I had an issue with the installation also. I used the spacer, not the bottom PI rail. Thought it wasn’t an issue trying to access the oil filter housing for future oil changes. Well it was. It took some effort to get it removed put back on. I had to file down the bottom side of the manifold. No more issues but this needs to be addressed for future manifolds produced.
Side note, the only way to get the manifold to attach to the head, is to use the provided spacer, which has seals on both sides of the spacer.

Definitely a strange issue.

Similar comment to the above... it's not clear in the post if the phenolic spacer was used, but it appears it wasn't. It will be impossible to access the oil filter without the spacer as it takes substantial effort to remove filter even with the spacer & rail in place. Spacer won't solve your problem since it sits on top of rail, but wanted to mention before you get this all put back together. It may be possible to put the spacer under the rail, but don't remember if that's possible.

Spacer is used. I was able to finally get the intake manifold to seal after slowly grinding down PI plate.

I considered putting spacer under PI plate, but is it not possible because of bolt pattern. And that would make it even more difficult to get oil filter out. With the way it sits now, the oil filter hits the manifold with probably less then 2 threads remaining. It's almost like if i didn't shave the PI plate down, it would clear. And I'm beginning to wonder if maybe all the PI plates are hitting the manifold allowing them to somehow seal and lift the manifold to clear the oil filter just enough. It's worth mentioning that I did not try to fully install the PI plate until I made it clear the water manifold.

Sounds like you have a one off issue. I checked my photos with the manifold off and mine looks just like your pics. I do remember having an issue getting it seal properly at first and now wondering if I was having a similar issue but got it to fit with some finagling. You took a lot of material out so I think you might have it worse. Good luck on this.

I do not have clearance issues here. Reserving this spot to post some pictures under the IM with a borescope. Mine is a 2020 model.

After reading the comments again, why don’t you use the provided heat spacer, which is thinner than the PI plate? In other words if you bought the kit new, it should have come with two options to run PI, or am I missing something here?

Seems it would be easier to run or use the top rail instead of the PI plate. This might not still allow the needed clearance for the oil filter housing clearance. I chose this route, and still had to shave a portion of the bottom corner side of the manifold to get the oil filter housing out without any issues. It’s tight, but definitely better than what it was.

I am using the PI plate (i call it a dummy plate cause port injection is blocked off) AND the phenolonic spacer (thermal spacer you're referring too). And I'm still stuck with 1-2 threads left when pulling out the filter.

I am fairly certain it's not really possible to not use the PI plate. As the intake manifold pattern doesn't match the head intake bolt pattern. The PI plate converts the bolt patterns to work.

Ignore the measurement, that's without it bolted down, but that's the best picture I have right now with the phenolonic spacer in.

I went back and looked at my photos. You are correct. I did have to use the PI plate and the spacer, due to the bolts lining up. I like the idea of them including the two options with the kit, but not the tightness for the oil filter housing.

Patiently waiting/interested ?

Patiently waiting/interested ?

I bought a borescope the other day. I'll check mine out too. I can't change my filter either without loosening up my mounting bolts, but that only takes 5 minutes so I'm not worried. I took my manifold off this winter to make sure I installed it properly and I did. I watched the install video so many times to make sure I didn't flip something wrong or skipped a step.

I would still recommend the manifold. 4.5/5 stars. Lost a half star for not being able to remove filter without loosening the manifold.

Any updates on this?
