1.8T oil pump and filter adapter conversion

**aluthman** · 12-07-2015 07:59 PM

Who has done this conversion and what were your results? I'm trying to decide if I should go this route or not. The idea sounds great on paper, but the two people that I know of that have tried it ended up with low oil pressure issues. I'm trying to figure out if these were due to something else or if they were a direct result of the conversion. Whatever info you have, lay it on me.

**abzoni** · 12-07-2015 08:21 PM

low oil pressure issues? i thought the issue was supposed to be high oil pressure

anyways, mine hasn't given me any issues and i don't get the excess vibrations that some people experience. in terms of results...it works? i did the conversion so i don't have to worry about the 2.0t pump failing again, but your goal might be different.

The two people you know that did the conversion and had low oil pressure issues used the IE oil filter adapter and an 06A oil filter housing/filter?

Yes. Mec wiped some bearings as a result and EPY caught his before any real damage was done. IIRC, EPY added a shim to the spring in the 1.8T filter adapter to boost pressure. I'm currently trying to get in touch with him since he's been AWOL from the forum lately.

**Axis** · 12-07-2015 08:42 PM

^^ Wow, I'm 1500km from having mine done and was positive that when using the 06A oil filter housing, everything was safe. I'll subscribe and see what info comes out.

I don't wipe. I only crush, like i crush box left and right bruhhh

**mec** · 12-07-2015 08:46 PM

Lets also add in that I was a noob that had never even spun a wrench and I built my engine and did an oil pump conversion at the same time and installed a turbo so its pretty likely anything else could have caused my failure

**aluthman** · 12-07-2015 09:12 PM

I think I'm going to do the conversion, but I'll be adding an oil pressure gauge to my shopping list.

**audihere06** · 12-08-2015 01:36 AM

Samsonknight has it on his with no issues.

Setails on the setup you tried?

**audihere06** · 12-08-2015 10:02 AM

First just the pump, then the filter housing and everything. Still couldn't get the oil pressure right. But Im not sure if it was all the conversion that was the problem. Turns out the guy who rebuilt my internals put the wrong bearings in it after he cut the crank. Long story short after maybe 2 hours of run time it blew up again and was beyond fucked.

Yikes. I'm glad I'm doing my own engine so I don't have to worry about someone screwing up my stuff.

**audihere06** · 12-08-2015 05:20 PM

But i added ie drop in rods while i was in there. Already have forged pistons because bpg engine. Ask samsonknight about his. He has probably 5k miles on his with the pump.

3000 miles on my conversion, no oil pressure issues. Installing 32DD oil pressure sensor relocation along an oil pressure sensor wired to my P3 as soon as I find an heated garage. Will provide cold start pressure, idle pressure, 3k pressure for those interested.

**audihere06** · 02-04-2016 11:54 AM

I have a full conversion kit for sale if anyone is interested.

I would also be interested to see what it is near redline and immediately after cutting the throttle from high load/rpm.

**Okedokey** · 02-04-2016 03:22 PM

Ok, so what is the benefit of the 1.8 conversion? Is the oil pump in the 1.8 better for some reason?

It doesn't have the integrated balance shaft assembly. It therefore is simpler and less prone to failure. It also reduces the rotating mass of the engine by a couple pounds and increases the oil capacity by ~2 quarts. The downside is that some people have run into oil pressure issues (both high and low) due to the differences in the 1.8 and 2.0 oiling systems. Some people have no problems with the conversion while others have wiped bearings because of it.

I'm in the very long process of my motor build but finally on the home stretch. Doing the full conversion using IEs parts. Hoping it holds together.

Did you go with the full crank girdle kit?

**Flexcj5** · 02-04-2016 07:09 PM

No girdle kit. Just the pump and filter adapter along with the the needed small parts.

When you get it installed in the car, I'd also be interested in how you setup you pcv/catch can.

That's assembly lube. It keeps the mechanic operating smoothly during assembly.

Definitely curious to hear what your pressures are.

I'm surprised how the 1.8t oil pump conversion thread keeps popping up. As far as I know, I've only done the 1.8t kit from usp and it is supposed to be pushing more oil pressure than stock, so therefore no need for oil filter housing adapter. I'm beginning to believe that I need the adapter to control pressure. What setup did mec and epy have?

**yeoj112689** · 02-15-2016 08:30 PM

So I am assuming you did not pull the pistons and such to install. Can you leave the heads on as well? I am not sure if I need it yet or not but I got a "oil pressure" warning light the other day when I went to leave for work so I parked it and took the girls car. I am going to hook up a manual oil pressure gauge to see if there are issues but I am assuming its not going to be good. I just hope nothing else is screwed up. I stopped right away and pulled back in my driveway so HOPEFULLY its alright.

EDIT: Never mind the question that was here I am an idiot :P

MEC's original was purchased by a Canadian, who will be installing it into his new motor from Slimjoker. And he really really hope someone can provide more info on these shims b4 he drops the motor into his car. I tried getting in touch with EPY about it and even posted a pic in my build thread specifically asking exactly where they went and what size shims or washers to use. Never got a solid answer. (Currently have access to any stainless part our brains can imagine due to career change)

I'll be running a pressure gauge aswell. On the dash and one under the hood off the turbo which will be mechanical pressure. No way to see mechanical gauge from cockpit though unless I decide to run the oil line into the cockpit of the car... Which if it lets go wud be a mess.

From what my friends doing these conversions local are saying, you absolutely need the oil filter adapter from the 1.8T to be able to have the proper oil pressure.

To be able to use one you need the IE 06F to 06A oil filter adapter. ~200$

4.5mm shim is what EPY used.

It goes on either end of this spring to increase the preload.

**yeoj112689** · 02-17-2016 02:49 AM

Random semi-related question.. if I am pulling the motor to drop the oil pan.. will a 1 ton crane do the job SAFELY? Also do our engines sit well on stands or are they too heavy?

I have never lifted a personal engine out of a car, only motorcycles, but I assume its basically the same difference. A DIY for the complete engine pull would be pretty helpful as well.

**aluthman** · 02-17-2016 03:22 AM

Yes and yes. HOWEVER, a 1 ton crane might make it more difficult due to the limited reach and height of the crane itself. I returned my 1 ton crane after assembling it and got the 2 ton because it is taller with a much longer boom.

I plan on pulling the front end off (bumper and all) because I needed to do the timing belt and such anyway. I just hate seeing it sit in the garage when I just got my JHM flash cable and tune... and HPFP upgrade... and coilovers... and rear diff mount....and test pipe.. in the mail. Perfect time for a oil pressure light right? Any suggestions on pulling it?

**aluthman** · 02-17-2016 03:30 AM

Haven't pulled mine yet. Maybe this weekend or next, depending on weather.

That's where I'm at as well. Garage is large but far from heated lol.

**aluthman** · 02-17-2016 04:57 AM

I have a heater but need the door open to have room to move the crane around. I can have the door shut for everything but the actual removal and reinstall.

**Flexcj5** · 02-17-2016 11:04 AM

Our engines are light compared to most out there. They sit just fine on an engine stand and a one ton hoist will do it but the two ton is usually more stable and has better reach.

**audihere06** · 02-17-2016 02:50 PM

I bought a cheapo engine stand from harbor freight and it was just fine.

Same here, I got the smallest one and had no issues what-so-ever. Our engine is light enough that it can easily be lifted by two people, even when fully assembled. After you remove a few parts, you can manage by yourself.

Someone should weigh one while it's out for shits and giggles.
