As far as v spark plugs go a mechanic friend vee-nothched a set for me but I did not find a difference in performance.

If you meant inline six and tapered seat plugs, then the answer is to use the plugs with washers rather than the tapered seat type. If you give the make and year of the engine, someone can give you the plug number to buy. | | | | | Joined: Mar 2005 Posts: 1,029 Member | | Member Joined: Mar 2005 Posts: 1,029 | Sorry about that, madtrapper.
I forgot that English is not your first language. The other thing an inline engine is called is a straight engine, as in straight six or straight eight, and flat is normally a synonym for straight, but not where automotive engine types are concerned. In an inline or straight configuration, the cylinders are all in a row, but in a flat engine the cylinders are arranged in opposed pairs.
Unfortunately, V-type aircraft engines are called inline engines to differentiate them from radial engines. | | | | | Joined: Apr 2005 Posts: 1,971 'Bolter | | 'Bolter Joined: Apr 2005 Posts: 1,971 | I think there may be benefits to these plugs, but the application of them in an old truck will yeild unnoticable benefits.
For an old stock truck engine, I would not waste my money. Standard plugs would my choice. | | | | | Joined: Jun 2006 Posts: 687 Shop Shark | | Shop Shark Joined: Jun 2006 Posts: 687 | Are you refering to the split fire plug? If so they work just fine. But the old origional plugs do also. So I really don't see any advantage of using them. I do use them in my sons dirt bike, they seem not to foul out as often when he mixes it to rich.
As far as the engine cleaner, do you mean inside the engine? If you need an engine cleaner inside the engine its time to freashen it up with an overhaul.
If you are talking about outside of the engine, I use Castrol Super Clean, I buy it by the gallon and use it straight. (no water mix) It will remove most any petroleum product, will clean the kitchen floor, removes all wax, and is biodegradeable. Cleans white wall tires with out scrubbing also.
