Tennant 6600:
1.6 Vortec engine woes

We have a Tennant 6600 sweeper at work (2007 model) with a GM 1.6 Vortec engine.
The engine has once again blown a head gasket. This latest makes the 4th time since the sweeper entered service in 2007.
From what I gather reading around the internet, this engine has a reputation as having "2 year head gaskets", and that sure seems to fit.
Another implication that bears out how poor this engine has performed for people who ended up owning one can be inferred by the fact that GM no longer even produces this engine and also that there are no longer available (so far as we can determine) any complete engines or long block assemblies left in market. It seems that all have been sold already.
Just yesterday I heard through a grapevine that a "fix" for replacing the GM Vortec with a Toyota brand engine has been developed and it is in the form of a retrofit kit.
Have any of you heard of this so called kit fix anywhere?
The person who told me of it yesterday is supposed to furnish me with a contact but I thought I would run it past this board as well as a sort of "verification/validation" thread.

HI, I read this with some interest, as I purchased 2 brand new 1.6L psi/gm's in 2009 for a generator application. (they were supposed to have been standard sae drive arrangements!) so as they are far from sae, I have been sitting on them, still in original crates, in my heated warehouse and am looking to sell. any interest out there?

none taken bb
my comments are based on my past experiences with engines from back a few years ago.
I know now a days with the changes in the market and how companies are farming out thier sources to other cheaper sources it most likely means the products have also changed, which they have.
Back in the day when they said 'industrial' and 'automotive' there was a distinct difference. I've seen it.

anyway its all good :o)
