I've been using a catch can for the last 40,000 miles - it is emptied approximately every 5000 miles. A large reason for the switch from the twin-turbo to twin-scroll turbo is cost and complexity. Discard all of the fasteners and replace them with new ones. Even though the N54 is more efficient when modified, each engine and its respective turbocharger set up will produce well into the range of 400+ wheel horsepower and torque. A auto shop gave me a estimate of about 5,600 for the motor and 1,400 for the labor in getting a new motor and swapping it ou with the old.
It could potentially be an oil lubrication problem, what with the car having been massaged around the Nurburgring once or twice The oil sump has been cleaned up with a view to getting a special oil pan baffle manufactured to prevent oil surge and ensure constant oil pickup. This is where I am at now. In the year 2008, Roman Abramovich was…. Best of luck in your decision on purchasing the car. Might leave it like that until both turbos installed. Fill the engine oil and fill and bleed the cooling system. Discard all of the fasteners and replace them with new ones.
Hopefully you have ironed out the issues by now. Do not work on your vehicle if you feel the task is beyond your ability. Per above, everything else has been replaced. There is also a belief that the recirculating crankcase ventilation system allows oil vapour to be deposited in the intake system and this exacerbates the problem of carbon build up. Camshaft lock installed Chainguide mounting plugs removed Timing chain tensioner removed, make sure to pump it a few times to evacuate old oil and also replace the aluminum seal.
You are right - the combustion chamber filled with oil is 5. Next remove the right side wheel well liner. Turbochargers spin at speeds of up to 10,000 rpm or more and require a very efficient oiling system. How do I know if I just need the wastegates fixed or if I need both turbos to be rebuilt? April 2018 — Solenoid valves replaced Thank you for the comment, P. The key to the additional torque and power is the twin-turbochargers integrated into the exhaust manifolds.
Then feed the harnesses out from behind the cylinder head green arrow , removing them from any mounts and snagged areas. The cylinder walls may be scarred by carbon from the upper part. Let us know what you are looking to spend and people on here will let you know if you are being realistic. In the meantime, there are a few more pictures of bits of my car on the floor. Find how right I'm considering picking up a used 335i or 135i. August 4, 2016 Followup from the Pelican Staff: Still need to determine what is causing rough running. Otherwise good on you for tackling the rebuild and conversion.
I went immediately to view the engine in person. Then pull the oil line out of the crankcase. This is because the extra boost pressure created from these tunes puts more strain on the turbochargers, creating accelerated wear and tear. You have to ascertain what the smoke actually is. Figure 3 Working at the vacuum reservoir, mark the vacuum line locations. Since neither of us had any luck in removing the bolts holding the oil supply to the turbos, Bentley to the rescue! If the line is damaged in the slightest bit during removal, replace it.
Big work and cost involved there Tony. The easiest, most effective, and most efficient way to remove this carbon buildup is through walnut blasting! How are you getting on with the Okada coils? Backstory: 3 months ago my 135i spun the cylinder 3 rod bearing at 95,000 miles. Spun bearing or blown turbos or what? The N54 engine never idles completely calmly. The pictures below show the cylinder head as it came off the engine, and the state of the valves. Clogged injectors can also cause a bad fuel spray patter. Are there any specific issues that might pop up that would be related to the Dinan upgrade? The process involves a complete disassembly and cleaning of the head with leak, crack and pressure testing.
. November 8, 2016 Followup from the Pelican Staff: Thanks for the feedback. Figure 18 With the rear turbocharger removed, you can now remove the front one. Clean all sealing bores and surfaces using a lint free cloth. June 7, 2018 Followup from the Pelican Staff: Thanks for the additional info and feedback.
Give The Pelican Parts parts specialists a call at 1-888-280-7799. That may explain the abnormal wear on the crank journals. The net result is a really significant increase in performance with absolutely no drawbacks. The engine internals looks like shit considering the low mileage but being punished on the Nurburgring accelerates the wear. Remove the coolant pump and thermostat. I did not own too many cars prior to my 335i, however, I can attest to the fact it is the most mod friendly and community friendly platform I have experienced.
