Have any of you had a issue with a intake  gasket rupturing  & hydro locking the  Motor?  I was told that's why my motor won't turn over ( The plugs haven't been pulled yet ) I attempted to start the engine  , It did start but only just briefly , It just kind of dieseled about  3-5 seconds  & then it just died  , I tried to start it again & it would'nt even turn over . I could hear the bendix gear striking the flexplate & I could tell the engine for some reason was binding or locked up.  I was already planning replacing the  OE timing chain , So I am going to have that done as well as Maybe a lil head work too , I can't find  any heads I can buy to start the process for a reasonable price ...so I'll just have the stockers  rebuilt  , Maybe some pockect porting,  ( Suggestions needed )  bowl blending , & maybe even some match porting  ( Intake & exhaust ,Runners ).

I'm looking for any & all input  from  my fellow C4 owners , What sensors should be replaced while the motor is apart  ? where are they located  ........ Just anything that will help make a not so smooth task , just a tad bit of  a less nightmare . Is it worth swapping in a new cam ? What cam could be use that is  C.A.R.B complient?


Thanks

Big Mike

Uh...no. Not really sure HOW that could possibly happen. No way for coolant to enter the cylinder from the intake. You sure they didn't say head gasket?

That's the  hundred dollar question here  Adam , I sounds crazy to me also.... I think it has a blown head gasket  , The funny thing is the day before I last drove it , It was running great  ....And the next morning trying to start it @  2:00 am ...It just caved in on me  , I felt bad for my Neighbors because My other commuter was down also,So I had to start my Very Loud Chevelle up & wake the whole Neighborhood & let them know I was going to work.  Is their any advise you could share with me on the other matters also please?
