This is a dedicated go-fast car at this point. Will keep you guys updated with that. Please call me direct 888. I am not sure what the repair will cost in your area.
I assumed it was from a previous repair and I did not have the funds at that time to tear my engine apart for a proper diagnosis so I drove it as is for months until now. And is the same torque used for the other three bolts like it that are under the valve cover? Jointing torque and angle of rotation must be observed without fail. The metal rectangurings that are inside the camshaft bearing ledges which house the camshafts originally equipped on the N52 and N54 engines wear down with time, allowing play within the bearing ledges. Summing up we can say that this engine is rather reliable and powerful. I would suggest you grab a repair manual, you should own one. Its incredible that no one has put these people on blast yet. Clearances are on points so far but of course we will remeasure prior to installation.
The N54 has two small low-pressure turbochargers to minimise. You think any of these guys editing files on forums calling themselves tuners will be able to do a cam tune? Read the next instruction before you begin loosening. Would appreciate what you have to say on this. Remove all journal caps except A3, A5 and A1. It is made of aluminum with cast iron sleeves and crankshaft. Will keep everyone updated with the entire process! The boost pressure is 8.
However the difference between M54B25 and M54B30 is in their displacement. I complied and paid a large portion of the total to get it moving. I'm guessing these cams are good for ~25-30whp at peak power the same boost level given sufficiently capable turbos. These type of comments add so much to the Pelican tech community. Definitely looking forward to results! They can help you find the right part. Is this normal for my situation or do you think that the threads of the bolt have snapped as well? Ok well whatever the error, I can not find anything on Schrick cams actually being used in a N52.
N54 is a twin turbo charged Inline-6 engine. Give our parts specialists a call at 1-888-280-7799. Connecting rods have also been replaced with longer ones M54B25 connecting rod length is 145 mm. Could find no additional information online. Give our parts specialists a call at 1-888-280-7799. The warranty period for the was also increased, to 10 years or 120,000 mi 190,000 km. Since the N54 is based on the older engine, it has an aluminium engine block instead of the magnesium alloy used by the N53 , a displacement of 2,979 cc 181.
Surely a new bolt would not sheared like this under normal load and torque spec? Thanks for the follow-up, I over torqued the bolt the first time thinking it was 7nm and additional 90° jointing torque. Install the cam so that the side of the flange with the 2 holes is facing up and angled toward the exhaust cam as shown. For now I attached more photos of how the head and valves looked. Then, what is left of the bolt will just spin out. Even though there is lube on the lifter faces, I will usually smear some assembly lube on the cam lobes as well.
The final model powered by the N54 is the roadster, which was produced until 2016. January 29, 2018 Followup from the Pelican Staff: I don't have a part look up tool to find part s, I am the technical advice guy. Some shops will tell you right away that both Vanos units must be replaced! I want to make this thing virtually bullet proof. If you find this bolt broken and there are no other symptoms, have the bolt replaced as soon as possible. If the A1 cap does not rise equally each time you loosen the nuts at A3 and A5, stop and find out why. That is the torque I supplied. The picture is of the intake cam, but the same idea can be used here on the exhaust cam.
I put about 30 miles on the clutch and brought the car home right away to get started on the! A3 and A5 are the only journals that are carrying any load with the camshaft in this position. Posted in: , Tags: , , , , , , , Hey man, I saw your write up and decided to go the same route with my 335i. Journal A1 has a thrust surface that can possibly hang up when the cam starts to rise. Replaced the shifter bushings and transmission mount. Hopefully I didn't damage the engine block.
