JJC Posted October 3, 2017 Report Share Posted October 3, 2017 Question for the knowledgeable. Are all 4 pot standard tin sumps the same? I would assume so, but have often assumed incorrectly before. Reason for asking is that the oil leak in my 4 defeats all attempts to stop it. Latest thought is cracked sump and I just happen to have an early standard sump lying around.

TRseks Posted October 3, 2017 Report Share Posted October 3, 2017 (edited) Is it not possible to weld it, thought these are mild steel? But yes, probably easier to replace... Magnus Edited October 3, 2017 by TRseks Quote Link to post Share on other sites
Ian Vincent Posted October 3, 2017 Report Share Posted October 3, 2017 There are at least two types of pressed steel sump, I know because I have both. One has a parallel threaded boss for the drain hole and one has a tapered threaded boss. My original sump had been repaired (brazed) and to avoid the possibility of it splitting again, I picked up a second hand one on the Bay. It turned out to have the parallel threaded boss and I had a hell of a time trying to find a plug to fit it, in the end I went to a plumbing supplies shop.

john.r.davies Posted October 3, 2017 Report Share Posted October 3, 2017 First Q., JJC, where is it leaking? A clean and a dusting with talc might show it up. Not familiar with Tr4s, but a pressed steel sumo is a pressed steel sump. Have a DPO tightened the bolts so that the flange is belled around them? Dressing the sump by light hammer blows against a 'post' can get it sealed again. John Quote Link to post Share on other sites

So otherwise they all fit. Good news! JJC Quote Link to post Share on other sites
