Knocka knocka Knocka Knocka waiting for the boom. So, I was chasing valve guide seals thinking this beast has a 'normal' problem. Then I rerouted the CDR hose from the air filter housing to a road draft tube. The smoke trail is similar to the wake behind a PT Boat in WWII. Along the lines of the ocean wake following the HMS Queen Mary. Occasionally the engine would bang and had the familiar ring of a rod knock. Then looking at the oil pressure gauge yesterday, I saw it drop off to the low side of "Normal" at road speed. Then I eventually came to a red light and the oil pressure came up. Yeah. A rotating rod bearing came to mind. Not to mention the rod knock noise. So, now I am looking at a rblt engine fora few more bucks and I really should look at a head stud kit. I am impressed with the $532 dollar price tag. A fast internet search finds me an engine rblt for $3800. (Quality? Think I will go with a local shop and 40 plus years experience) Add a Rblt turbo for longevity insurance and another $1000 Now add the $532 head studs and this is getting a tad bit expensive. Bone stock engine and the head studs are an insurance factor. Oh yeah, Maybe I should add an oil cooler to this engine rbld. Add what, another $250? The IP is new rbllt. Injectors, glow plugs, filters, belts, pumps. . . This is getting fun. Up to the $5500 price range. Add a crank and that might bump me to $5800. At my young age, I am not interested in playing backyard wrench outside in the weather. I did that a few years ago. If I can get it done cheap enough elsewhere, so be it .
