Noticed a couple drips under the engine, and it didn't smell like trans fluid. So I of course suspected a rear main seal leak. Now this engine only has just over 2K miles on it from a total rebuild. and I just had it out to repair a broken rocker arm stud over the winter. I didn't remove the flywheel at that time so the seal hasn't been disturbed since being put together.
 But when I pulled it apart I found the area below the seal was dry. closer inspection revealed that the oil galley plugs I installed had leaked. Definite wet on the left plug in this picture and a little oil on the far right one. I used some liquid Teflon pipe thread sealant when I put them in. I was thinking of using some of the HondaBond case sealant this time. I used that on the case halves. and it seem to be holding up okay.  The seal I put in originally was a Victor Reinz seal and I ordered another before I even pulled the engine. Now I wonder if I should just leave that seal in? it only has 2K miles. OR pull it out replace it and maybe check the crank endplay again while I have it apart. I am leaning towards ... Leaving well enough alone, and just resealing the oil gallery plugs. and leaving the rear seal in there. What is your opinion ?? |
