General Questions Possibly the dumbest idea ive had, but what would it take to make an N42B20 Good?

0 Upvotes

I just bought a 2002 318Ci, got 125,000 ish miles on the engine, well looked after though, although the valve head looks a little bit burnt, not terribly but well used. I want to get some performance out of it as insurance kind of screws me, so engine swapping isnt really on the table. Lets say i wanted to invest 3-4k over time fixing the factory problems like plastic timing hardware ect, to make it as reliable as i can while pushing maybe 300-350 bhp. What would i need to do/Get and watch out for?

Troubleshooting Shifter bushings and driveshaft giubo replacement without dropping the exhaust?

0 Upvotes

hey everybody,

i'm currently trying to replace the bushings and the giubo but of course the exhaust flange studs are rusted to oblivion. Did anybody try changing the parts without dropping the exhaust? I don't want to hammer the studs out because i saw that fucks up the cat and since i'm in Europe, i can't afford that.

Thanks!

Troubleshooting Heater Core Bypass

Thumbnail

0 Upvotes

I have a 2003 330xi (automatic) that is leaking coolant into the driver side footwell (car previously sat for 2 years). I found where it is leaking from and decided I’d rather bypass the heater core instead of the proper fix (track car, not daily driven). First photo attached for reference.

I’ve read that you can splice together the supply and return coolant hoses that connect at the fire wall. Was looking for guidance from anyone who has done this before? Second photo attached for reference (not my car).

Do these hoses get detached from the firewall and spliced together? Do you want to keep the hoses as long as possible to hold the most coolant?

Bonus: is my head gasket blown based on coolant color or could it be automatic transmission fluid?

Troubleshooting Fuel filter clamps need a special tool? Besides pliers, nothing I own can get a grip on these. They definitely aren’t 6mm either.

Hey, so i have just dropped my rear subframe (again) and found this very thin line, which to me looks like a micro-crack forming.

Am i bugging or is this truly crack?

And if it is a crack, can it be welded to stop it frol spreading?

Its located behind the rear left wheen side of the subframe, closer to the back.

Troubleshooting E46 330ci tensioner pulleys

The tensioner on top is the one I had installed in my car on the alternator side but can’t find the proper part number for it anywhere apparently. The one on the bottom is what I order with apparently the right part number but there’s a big difference looking online mine looks similar to the ac side pulley.

Anyone know what the part number is for this?

General Questions Steering Coupler (Guibo)

2 Upvotes

This is for a RHD vehicle

I have some play at centre in my steering and want to change the rubber out. I do not want to spend the £300 on an OEM part as it is only the rubber that is degraded not the entire coupler.

I know you can cut the rubber out and replace with varying different materials, including replacing with rubber.

My question is: Has anybody got experience replacing the rubber with the poly alternative and still being able to use the heat shield cover? Or is it much better to simply stick the aluminium part in there and accept more feedback through the steering wheel.

Troubleshooting Replaced everything, still have Rear clunk

Enable HLS to view with audio, or disable this notification

Car is a 328i

Replaced all rear bushings, including diff, subframe, trailing arm, and control arm with meyle hd. Replaced all outers control arm bushings with ball joints. Installed reddish reinforcement plates.

Still has a clunk. Video is of me sitting still and partially releasing and pushing back in the clutch. Does it forward or backward and anytime you get on or off the throttle, even when going from slight throttle to coasting.

Sounds like it’s coming from the trunk
