My Redline just turned over 71,000 Mi and I am having a problem with engine misfires when the engine is cold. Seems to go away after warm-up.
I am still running on the OEM spark plugs. I have not checked the compressor inlet piping for any oil coating. I also have not checked the PCV check valve on the compressor inlet pipe to see if it is passing oil into the pipe. See "Check Valve" in the Post #1 photo in the excellent post by TS in the Sol Forum: Why & where you should/shouldn't run an Oil Catch Can (OCC) on an LNF kappa - Pontiac Solstice Forum
I have read about the LNF intake valve coking/deposition and I am wondering if anyone on this Forum has personally experienced fouled intake valves? If yes, what were the symptoms?
If so, was it detected by a "scope" check or complete intake manifold removal?
Was the work done at a GM dealer?
Did they do the walnut shell blasting to remove the deposits?
Did you have to pay or was there any warranty or discount available? (I have a GMPP Extended warranty which expires in April.)
Does anyone know if the valve cleaning is/should be covered by GMPP Warranty?
