Got a minor leak from front crankshaft oil seal, is slinging some oil and messing up engine face. L/M dealership quoted me $257 to replace it. Rock Auto sells the seal for $15 - $17 + shipping (PTFE is the more expensive one) or can get from dealer or other FLAP, and I can get inexpensive pulley remover and seal installer from Harbor Freight Tools and/or ebay, so I'm gonna tackle it myself.
Question: when I pull the old seal, will engine oil come gushing out? Should I do this at an oil change so block is drained prior to removal? I'm using Royal Purple, and don't want to waste it.
2nd question: who makes the best quality seal? What is best material? Should I get the PTFE one under the assumption higher price is higher quality?
3rd question: should I replace anything else while I'm there? Doesn't look like there's anything, short of breaking open the block (and I'm not gonna do that).
TIA.
