hi guys does anyone know if the oil filter housing for a 1961--1965 401 is available new anywhere in the US ? Alternatively does anyone do a remote oil filter kit ? anyone maybe got a good second hand one and happy to post to Australia ? I have just discovered mine is cracked and nailhead parts are not very easy to locate in Australia thanks all
The 3 main Buick guys on the net are Centerville Auto Repair, TA Performance, and Best Offer Counts (E-Bay mostly). Mid 61 thru 66 will be the same.
Try searching here, too, though, I think this may be the same seller as Best Offer Counts mentioned above: https://buickfarm.com/
A lot of them on Fleabay: https://www.ebay.com/sch/i.html?_nk...sacat=0&_from=R40&_trksid=p4624852.m570.l1313
Most E-Bay sellers will not ship internationally but check with the Martins @ Centerville. I will also look and see if I have one. I believe I gave my spare one to a fellow Hamber a couple of years ago.
My 62 401 uses a spin -on filter and I see on the Centerville site that they list 3 different sizes of spin-on filters for the 401 Nailhead (different lengths) Do some 401 Nailheads use a cannister style filter? @buickwagon if your housing is cracked why not get it welded by a top quality welder?
^^^^ The oil filter housing design changed in mid 61, so the early 401s had the earlier longer style. Oil pumps changed in 62 as most of the engines used a center sump pan. Wildcats used a rear sump pan with a different pickup on the "new" style pump. The earlier rear sump pump is getting rare as they are no longer produced. Melling makes the 62-66 pump. Cracks in the housing usually happen where the relief valve disc sits and is not repairable. External cracks maybe.
