Decoding/Numbers / Re: 1969 03d clarification needed

« on: January 16, 2024, 09:04:06 PM »

I have a 03D car as well.  The VIN is N6180XX and when I got the NCRS shipping report back in stated that the car was produced on Friday March, 21st, 1969.  Based on William's comment it sounds like my car got moved through the production line rather quickly.  I wondered if that was doable or if there was an issue with the dates.

Maintenance / Re: Engine Oil Additives

« on: October 16, 2023, 02:37:28 PM »

Thanks everybody for the comments and suggestions. I just had the oil changed and I used the Valvoline VR1 10W-30 racing oil which I believe has more zinc.   

When we took the cover off and had the car running you could hear a small tick coming from the number 1 cylinder.  When we tighten the rocker arm it went away but after about 5-10 times the small tick started to come back.  Pretty sure it is related to a lifter and nothing else but I'll keep an eye on it. Actually sounds a bit worse with the valve cover on. 

I really want to avoid tearing it down.  I don't believe the engine has ever been out of the car and really want to avoid that if possible, at least for now. 

I'll look into the Marvel Mystery.  Any other suggestions?

Thanks again!

Maintenance / Engine Oil Additives

I have a 1969 Camaro with a 396/325 engine that we believe is all original and has a documented 41,000 miles.  Over the course of this summer it seems to have developed a slight tick.  I had it looked at and one of the lifters is weak or not getting enough oil and is creating the noise.  We pulled the valve cover and it seemed that there wasn't much oil coming up from the pushrods.  I don't believe the engine has ever been apart and judging from the condition from inside the valve cover it very well could be all the original lifters and never cleaned.  The question is, should I add in some sort of additive into the oil to see if it would clean the sludge out a bit?  Could that help the ticking noise? Sorry if these are dumb questions, just trying to learn a bit more about the
