Prophecy, couple of observations. Auto-RX will help you here. If you had left this engine to its original condition it would have cratered soon anyway.
You have one of the most severe sludge obstructing problems I have seen. The mechanic in me in screaming to dissassemble and manually clean, the analyst is crying... Dirt, cheap overused oils, lack of maintenance, possible coolant ingress, wow what has this engine NOT been exposed to?!
Key points and areas to pay attention to.
1) auto-rx can't work if oil flow is obstructed or interupted. Mechanically clean whatever you can and have access to. DONOT drop any goo into a return port.
2) use a thinner oil preferably non syn 5w30 or 10w30. The Delo 400 15w40 is too thick for this engine design attempting to disperse that trash.Even a HDD 20w20 would work well here for cleaning and rinse phases.
For all SEE NEW MORE EASILY UNDERSTOOD COLOR CODED INSTRUCTIONS ON THE AUTO-RX WEBSITE.
3) Keep the oil filter fresh, change it as often as required. In this SPECIAL case no longer than 500 miles until cleanliness returns to normal.
4) be patient as the chemistry can protect against damage but not if you overload or slow oil flow, AUTO-RX rides in host oil, if that oil flow is interupted RX cannot be expected to clean and protect, since it can't get to problem areas.
5)Keep a 3 ounce maintenance dosage load of RX in the host oil even in rinse phase and AS LONG AS IS NEEDED UNTIL cleanliness is returned to normal levels. Retreat/clean with RX as needed.
Keep us posted.
FYI I have had trouble getting hold of Frank too and found out that cancer and chemo treatment is the reason. He will respond.
