Hey guys I just did the ccv mod with the catch can from tractor supply and all 3?4 inch hose and after that (and before test driving it) I sprayed down the entire intercooler pipes, spider, hpop, and the valley with brake cleaner to remove all the oil and grime I could and search for my long lost oil leak. Well found the hpop line fitting is the oil leak but then I test drove it and could only hit 15 lbs at wot and before I always hit 18 lbs as the tune is still stock. Im wondering if either the catch can is too small and holding backpressure on the engine or if I got brake cleaner in one of the sensors or something. I have no idea where to even start looking. I checked the red tube from the wastegat all the way to the sensor on the spider (as I had it off to do the ccv plumbing) as the green tube too and they both look fine. The ccv mod comes out of the breather then up to the catch can mounted near the top of the firewall then then a hose from the canister back down to the stock hose mount in the intake. uphill then downhill so there isnt anywhere for any oil to (puddle) . Any ideas on what would or could cause this 3 lb loss of boost or where else to look would be greatly appreciated. thanks in advance:fustrate:
