Hi Guys,

I'm new to this forum, but have been riding Harleys in Europe since 1982.

I recently had to replace the engine in my 2001 FLSTC, due to a catastrophic inner cam bearing failure which totally destroyed the motor at 42,000 miles.

I ordered a brand new 103" motor from Latus HD in Oregon as used in the 2005 CVO Fatboy, had it shipped to Spain where I currently live....From the very beginning the engine has had the dreaded oil "sweat" coming from the left side rear cylinder & also from the front left cylinder...I'm pretty disgusted with HD, 1st my well maintained 88B destroys itself at 42,000 miles & the brand new replacement leaks oil.

I've now completed over 6,000 miles on the 103 & the leak doesn't seem to be getting worse...Just damn annoying is all!!!

I was just wondering if anyone else has had a similar problem?

So it's not a gasket leak you're reporting but a porosity problem?  Many of us here can remember when that was a fairly significant problem for the MoCo.  Can remember it coming up again a few times early in the 110 run. 

If that's what you've got we both know all I can say is sorry.  As there's nothing that can be done about other than replacing the porous parts with new pieces that were better castings.

Thanks,

I have heard of the porosity problem, I was hoping the was caused by excessive assembly lube at the factory. I spoke to Latus HD where I purchased the engine & they apologised for the problem & sent me a top end gasket set. They also informed me that some new engines had the small o-ring missing on the oil drainback dowel at the left rear of the back cylinder....I'll wait until the winter & then take a look......

Whether it's a porosity issue or the more hopeful leak from a gasket or o-ring is something that should be able to be distinguished.  Very thorough cleaning and some very careful viewing.  Will keep my finger crossed it's a simple leak.
