Gary Lewis Posted May 3, 2021 Share Posted May 3, 2021 Update! Here is a new pic after the undercarriage was cleaned. Any thoughts? It can still be the rear main or the back of the intake manifold. If either leak the oil will show up there. Link to comment Share on other sites More sharing options...
ArdWrknTrk Posted May 3, 2021 Share Posted May 3, 2021 Update! Here is a new pic after the undercarriage was cleaned. Any thoughts? I would be looking on the topside, for a leak at the rear of the intake. If there is no oil there then it is almost certainly the RMS or coming through the crank flange bolts. (I forget if your engine has gallery plugs behind the flywheel) Link to comment Share on other sites More sharing options...
Machspeed Posted May 3, 2021 Share Posted May 3, 2021 Update! Here is a new pic after the undercarriage was cleaned. Any thoughts? Curious as to how many miles your truck has on it? Mine, also a 351W, leaks there too and it is a rear main seal. Drives me crazy, but I'm not pulling an engine to fix it. Link to comment Share on other sites More sharing options...
