Hi guys just though id post up 2 oil pans that ive been working on. One was a complete failure it couldnt even fit in our r33 skyline. But the other one fits perfectly. Only the trap doors and extended oil pick up has to be made and i can close it up. Note i suck at welding so this was a first for me.

Please let me know what you guys think. I have some race fab oil pans for my rb26 and i was planning on buy one for my rb25 but takes to long to reach and i just wanted to give it a try. Oil pan on the right is a disaster. I suspect that the good creation on the left will hold 8 to 9 quarts of oil. In addition to the oil pan like i have poated before we made a custome oil drian that we made to flow the extra oil from the rear of the head. All were made from stainless steel. Sorry but i dont have photos of the drain with the number 10 fittings welded to it. I just have photos of the mod and the box we made. Oh we make these boxes to catch a large amount of oil and use the weight of the collecting oil to force itself back to the oil pan. From what we have tried this works the best keeping in mind we alsovent the block for breathing. We also return from both sides of the block from this box. From my personal experiments the rb25 has a way bigger oil blowing out issue than a rb26. I feel its because of the 3 oil entries to the head even if its restricted. So here goes

Finally finished the oil pan, tested for leaks and juat have to pain it now. It holds 9.5 quarts of oil. After i was finished i only found 3 very small leaks not to bad for a first time welder:D

I also extended the oil pickup. If you look closely to one of the photos its a perfect fit. Center and to the very bottom of the oil pan. I was very happy how it came out.

Thats all i had. Wasn't a problem really to weld mate. And yes stainless to mild. Though it would have been a problem at first. But my test pan that came out like crap was fine strength wise. Practice a bit and got it. This oil pan literally cost me about 100 usd to make. I found the stainless steel on the side of the road believe it or not. :D

      Out here E90s are the cheapest way into a sporty-ish car because everyone knows just how expensive the repairs can get. 8-10k USD for an automatic 335i.

      Noted. Have noticed BMW are more 'high maintenance' for sure. They've attracted my attention as I think the used car prices seem reasonable vs other options, and the extra quality overall vs a commodore / camry / corolla or similar of the same vintage is appealing, especially the interior, and they are more on the sporty side whereas the others mentioned can be more cruising or economical A-to-B only.

      Haha yeah I know, this is SAU after all, why are we talking about BMW's of all things!? I hear you on the 'don't have to worry about it' side of things. Having been fortunate enough to be have been able to buy a brand new motorbike or two...never really enjoyed them as much as I'd have liked as you worry so much about where you park it, will it get scratched, stolen, attempted theft, knocked over, etc...and yes dirty. Older less valuable bikes you can just go where you want and park it wherever and not really worry that much in comparison. And who cares if it gets dirty! Never owned a V8, and have had my eyes on VE / VF commodores for years but with their prices climbing so high, the M3 has come into focus more as prices are much closer than I've ever seen...is it a potential contender now?...of course need to factor in the S65 'maintenance' especially and like you said general M car 'tax'. One can dream anyway. But more on the reality front - did read the whole 330i thread as well and was a great read too, both threads enlightening as I've never even driven one of these cars! I do recall 330i didn't seem to have the same amount of issues for almost the same car (turbos and related differences notwithstanding)...perhaps down to getting it earlier in it's life so looked after better than the 335i? Perhaps so as your 130i has been good and quite similar, so finding a car that's been looked after well is the especially-crucial-BMW-first-step.

      Nice. Dont worry about the time of not running. My current skyline hasn't run since I bought it. About 8 years ago.

      It's also worth noting that I am heavily and unconditionally biased. I've had a lot of cars including some GTRs a fair while ago. I love my BMW's now a lot. They make no sense a lot of the time and the guys on here remind me regularly that I could get something else that does what I want better and cheaper. If you're going to take on an older BMW it's definitely a commitment. If you bail on it early you'll lose money and also the ability for it to put a smile on your face. Stick with it and it just gets better.  f**k I should get into advertising.
