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 ?? |

I use Teflon paste. Never had one leak. I won't use the vr seals either. The Sabo black is the only one I use

According to GoWesty the Elring model is the one to use. i finally found the article and their most recent update in 2021 now says it’s Eherling, the SABO not as good anymore due to age and degradation of the mold used to make the seal, so it’s no longer a perfect fit like used to hope this link helps others . https://gowesty.com/blogs/article-library/f...main-seal-story Phil -EDIT: sorry just saw that you had the same link imbedded in your post too. |
