When I use Lucas in the winter time, the car doesnt "crank" the way it should. I put the thinner in during winter, and it goes just fine.
I put the Lucas in during summer and its just fine. The recommended oil on it is 5w-30. During cold starts with heavier oil in the case, I get an annoying lifter tick.
Yes, it goes away after its warmed up, but I just dont like the sound.
After taking a look at those hoses and underneath the car. Besides normal road grime, there are no pools building and or noticeable wet spots.
With the excessive carbon build up, I am starting to think those Valve guide seals are starting to go.
As I havent got that far; Is there another test you can run to determine if the Valve guide seals are in fact letting oil past, until their warm enough to expand? It's an inexpensive ( relatively ) easy fix to do, as long as you have a lil spare time and the gaskets.
I also ran the bore scope through it again, and after using the BG 44K decarbonizer, the inside looks a lil' bit cleaner after 21 miles. I will see what it does after a full tank has run through with 92 octane.
I was surprised today to find out that based on specs and procedures, they recommend 91 octane. Weird...
