So, I was visiting another forum and the discussion of ecotec in champcar and lemons came up.

 

I know of a few that have dun blowd up.

 

Why?  And how did you stop it from happening again?

I think its an oiling issue that kills some of them.   Attention to detail in installation and using (at least in the Miata) the ecotech Miata oil pan has kept ours alive.   So far, knocking on wood....   Of and they really should not have the snot run out of them north of 7k all day long.....

The two biggest things in my experience are : 1) getting the oil pan on correctly and let it set up, a 2) get the gasket in the correct please in the filter cylinder lid.  Those are the common failure points in oil leaks.  It's complicated by the fact that it's extremely difficult to get a good dipstick reading mid-race.  Next to impossible.  SO you can't just "add oil".  Too much oil and it will blow back and drain out of the air filter.  ugh.

3500 gm v6.

 

The ecotec question came up from grm and I knew some people had issues with them.

 

I was curious, that's all.

There already is an ecotec powered 2nd gen rx7 racing champcar @cmi11er.

Oil is huge. Our first race (Gingerman '18) we spun a bearing due to 1) mismanagement of race/first race jitters 2) oil pressure sender backed out and we lost too much oil. Silly mistake. We pretty much continually lose oil pressure in certain high load corners, so we overfill and make sure it doesn't get too low. We are also running the stock oil pan, and @55mini noted last race that we might actually have the engine mounted at a bit of an angle which doesn't help our pickup. We also spun a bearing at a track day, but that may have been due to a poor rebuild done by the team. 

 

The second major failure we had was the adapter plate - ALLOW THE LOCTITE TO SET PROPERLY. A full 24hrs is required. Our bolts backed out, sheared off and destroyed an engine and a transmission. 

 

Our race at Gingerman this year was significantly better, but we had a mystery oil leak that we think may be a crack in the oil filter housing on the block. And as mentioned previously, it is VERY difficult to read that poorly designed dipstick. It sprayed all over the intake side of the engine, hence the suspected high pressure oil galleries.. TBD. But what finished the race Sunday for us was another broken trans.. ouch.

 

It's a hoot when it works! We just haven't been able to get the desired consistency. Finishing a race is tough business! We at least can say we finished over half of one race day now!
