  1. I know there are a lot of threads on this already, but I could not find the answer to the specific question that I had. That question being: can I reuse the water pump/housing, alternator bracket/alternator, and oil filter housing off of my G60 on the ABA motor? Or do I need to use the ones off of the ABA motor? The reason I ask is because the parts off of my G60 are a lot newer and look to be in better shape than those off of this donor motor that I got. Thank you all in advance! (also posted to VW Vortex)
  2. Hey guys, For anybody still following this thread, i made some headway. I replaced the ECU vacuum with OEM vacuum hose. It helped a bunch actually. Cruising around 2k RPM the car runs at ~14.8 AFR. When I’m driving and come to a stop, it will stay at about 14.5-14.8 AFR for a second but then slowly creep up to ~16-17.5 AFR. WOT is around 13.5-14 so still a little lean. I haven’t pulled plugs at WOT in a bit so I’m unsure if it’s just an exhaust leak causing my wideband to freak out or not but any opinions from anybody still following this thread?

  3. Hey guys just a question to gain knowledge: How can the bad piston rings in a couple cylinders cause lean running conditions? I’m just curious as to how these would cause that i guess. Thank you guys for all the help Sent from my iPhone using Tapatalk
  4. Thank you for all your information and help sir! It’s been greatly appreciated. I found that i can strap an ABA motor to my head as long as i put two head gaskets on if I’m running a smaller pulley. And slight modification has to happen to the distributor in order to make it work. But nothing major. Other than that seems pretty straight forward. So here’s the plan: Source a low mile ABA to temporarily be on the car and rebuild my bottom end in the meantime Sent from my iPhone using Tapatalk
  5. I did accidentally do the test on the wrong TDC sequence for cylinder one but that was quickly realized when the air was escaping out of the intake hose so i made sure to go according to firing order at that point. The lean issue i am assuming is coming from those bad piston rings as well as the misfire. Especially since once all oiled up and warmed up the misfire goes away. A solution i was told about is taking an ABA bottom end and strapping it to my head. It’ll be a temporary fix while i build my bottom end the way that i exactly want it to be. If i go to drive the car, would you say i should drop a little oil down into those cylinders to help lubricate them? Sent from my iPhone using Tapatalk
  6. Last compression test done showed 125-140 PSI in all cylinders
  7. No smoking at all out the back but does have a small misfire for the first couple minutes on a cold start Sent from my iPhone using Tapatalk
  8. Also 20% were still in the good range, the 40% was borderline between mild and low leakage. At least on my gauge. 50% was also in the moderate range but was definitely really far off from that 20% in those other cylinders.
  9. No no I appreciate it sir! So, I heard the air coming out of the oil dipstick hole. There wasn't air escaping anywhere else. I had each cylinder at TDC when testing so the test did take about an hour to do. So the valves should have been closed during this test. I can guarantee that there wasn't air escaping anywhere else as for that is the only spot that I heard the air escaping from. As for the PSI coming from the tank, I used enough air to zeroed out my gauge. I am not sure what PSI that was exactly but it was enough to have my gauge zeroed out.
  10. Hi Si, The two were cylinder 2 and 4. 2 had 50% and 4 had 40%. I did a compression test not too long ago - around the time that the issue began - and the compression was still good. Cylinder 1 and 3 had 20% leakage. I did it for probably a minute per cylinder to make sure the leakage stayed the same.
  11. So i am now in need of an opinion... I did a leakdown to reveal that two cylinders have piston rings going bad. No smoke yet, and no major oil loss yet. I am considering rebuilding the engine forged or swapping the motor. Anybody have any opinions for me? Sent from my iPhone using Tapatalk
  12. The injectors capping out at 3 bar would make sense as to why when i turned my fuel pressure down to 3 bar from 3.5, the AFR didnt change. I have a leak down tester on the way (should arrive Sunday) just to check for piston rings going bad, bad head gasket, or bad valves. Im not assuming any of these right off the bat just because im not losing any extra oil or coolant. Not sure if bad valves would show up on a compression test, but the last one i did, all cylinders were within 10% of each other and still within spec of the Bentley as well. I did not realize it does actually have a MAP sensor. I will double check the length of my ECU vacuum tomorrow to ensure that it is SPOT on. I also switched to a colder spark plug as recommended by multiple people for the tuned G60s. I appreciate all the help as well sir. I will update you with anything i find tomorrow when it comes to the ECU vacuum and on sunday with the leak down test as well. If you find anything else in the Bentley or come up with any other ideas sir, i would greatly appreciate any of it. Again thank you! Sent from my iPhone using Tapatalk
  13. Update: Checked fuel pressure: reading at 3.5 bar fuel pressure consistent. Turned down to 3 bar consistent. I am running stock injectors that duty cycle 80% @ 3 bar of pressure. Held down WOT switch and the AFR dropped to only 15.5-16. Something wrong with the WOT switch? Do I need the 30lb injectors instead to push the 3.5 bar of pressure? Here is a list of things that I have checked or done to try to combat this lean running issue (and just for maintenance as well) so far: - Fuel Pressure: checked - Injectors: New (stock size) - Pump: 5k miles - filter: 5k miles - Pressure regulator: New (adjustable) - Injector wiring: New - New Intake manifold gasket - New Vacuum lines - All new spark - Timing set to 6 degrees BTDC * Currently running basically all of the stage 3 kit from BBM with a 268 cam and 68mm supercharger pulley. Apologies for the long post. Anybody have any recommendations?
  14. Thank you sir [emoji1374] will do Sent from my iPhone using Tapatalk
  15. I will drive it though and have someone sit passenger and let me know how the AFR looks though for sure sir, Thank you[emoji1374] Sent from my iPhone using Tapatalk
