    Guys and Gals,

    When building a race engine do you guys do away with the oil slinger on the front of the crankshaft?

    I ask because ours came apart spreading metal all through the engine. When running the new style of seal I am thinking this piece can be thrown in the garbage.

    Thanks

    I wonder if it doesn't help throw some oil on the timing set and distributor gear? I know its a pretty tight fit where it goes in the front cover.

    John, I don't think it is necessary with the neoprene seal. I have noticed on engines with factory neoprene seals that they don't have oil slingers. I have only seen slingers in motors with rope seals. The chain is going to get plenty of oil reguardles. Jim Burek P.A.E. ENTERPRISES

    Jim,

    Thanks for the input. After thinking about the situation I kind of figured the same thing but wanted to make sure. I wasn't concerned about oiling because I have an oil line that will oil the distributer gear.

    Thanks Again

    I have seen a mod that taps into an oil passage inside the timing cover and then has a pipe that points at the chain/timing gear/fuel pump cam and lube it. That would completely make an oil slinger useless not to mention help keep the cam gear a littel better lubed..

    Not sure where I saw this, TA maybe?

    Hey John,

    There must be a reason why your oil slinger came unglued. Check you crank end play and make sure the thrust bearing isn't going away. Your crank may be walking forward, pushing the oil slinger into the timing cover!!!:eek2:

    This part should never come apart!!!! We use this part in every race motor that leaves the shop. We have only seen this problem once when a motor had a crank that kept walking forward due to a bad line bore!!!!
