Combustion leak test is the test to check to see if there is combustion gases in the coolant reservoir tank. Testing to see if there was a head gasket failure. The fluid was blue at start and blue at the end. Did not change colors. The last time I did a cylinder leak down test, all four...

Will @ Purple Drank. Nothing has changed, no new modifications since the turbo went in. I’ve changed the oil, found a couple vacuum leaks(MAF o-ring, pcv connection), but the ONLY thing that has been done since the turbo went in is tuning, no further modifications have been made or done since...

So, I’ve recently upgraded my Speed3 with the BNRs4, along with JMF manifold, CNT exhaust manifold, DM 3.5” intake, FMIC, has a Tial BOV, and the rest of the supporting modifications. Turbo has less than 1500 miles. Compression test and cylinder leak test were performed approx 2 weeks ago...

Awafrican concluded my testing today, results are as follows; Boost leak test yielded no leaks. Put approximately 30psi into the system and plugged it, no leaks and held pressure. Smoke/vacuum test - yielded 2 very small leaks on the hoses for the oil catch can. Smoke was leaking through...

So this is the current setup for the catch can, if you don’t mind, where would I put the check valve or additionally check valve? DM PCV plate/PCV valve >>> OCC (vented to intake pipe) >>> intake manifold with inline check valve

so what about the idling bouncing around when moving the steering wheel? And AFR kind bouncing during and going from a stop? Assuming where you said it’s in your tune, I should tell my tuner ?

@Enki so, this is bad? Sorry if I’m not fully understanding. First time going this far with the modifications and tinkering. Is this bad? Or something I need to notify my tuner on? Or what should I do? Thank you for any input.

@Awafrican so pretty sure I found the leak, right on top of the intake pipe. Not something I like to admit, but mistakes must have been made. The MAF o-ring was broken and the screws loose. Not sure how that was missed or happened but it’s fixed now. But I have another question, I have a BNRs4...

Hoping to get the boost leak test done today. I’ve been away doing army crap for the last several days.

My apologies, didn’t see the link before. Just started using the app vs webpage. Still getting use to the interface. @Awafrican @Enki thank you both, I’ve ordered the Treadstone honeycomb from that link, in addition to a few other things; HPFP rebuild kit, check valves to have on hand. I will...

Perfect. Thank you, I will do this immediately. Where can I find that honeycomb?

Additionally, this is my single can can set up; PCV to OCC to Intake manifold. The OCC is VTA but with a check valve just under the filter. There is a check valve inline going to the intake manifold. Not sure if that matters. It’s been perfectly fine up to this point, but I’m not ruling anything...

Copy. I will do the PRV test later as well. To the air straightener, no, it the wide open 3.5” aluminum pipe with the massive cone on the front from DM. No further alterations were made. Used the supplied O-ring for the MAF. Greatly appreciate the input, making a list of checks to do after...

I’ll check out the air filter, it should be clean, it’s only been being used less than 2 months. I’ll get the boost leak test done as well, and return with results. Additionally, would any fueling areas be of concern? O2 sensors on back of down pipe throwing off AFR? Fuel pressure relief on...

I have not performed a boost leak test, yet. Currently on orders for the weekend. But on the to-do list. The MAF was cleaned and new o-ring installed when I did the DM intake. Below is a list of all the modifications I have done. BNR s4 (11/25/2023) Bosch 3 Bar MAP (11/25/2023) XS Power...

Hey guys so here’s the deal, something’s going on with the speed, but I’m not sure what it is. I’m getting an intermittent vacuum leak, that causes a lean status. While driving, there’s no issues. It only occurs are idle or when stopped. I will add that when the AC compressor turns on, it also...

Hey Geoff, you may or may not remember me, you helped me several years back when I was in Michigan. Drove up for an oil housing conversion and we ended up having to retap some holes…anyways, wondering if this “oil trick” is still a viable working solution to try and fix compression. I see you...

Followed the tutorial to a “t”…sorta of. I missed the part where there’s a bolt on the front of the transmission to remove, I’m not sure what exactly it does but I can only assume that it would have made my 45 minute fight a bit shorter. But, I replaced the seal, bearing and the breather. Went...
