Interference. They like to smash valves. I've seen one that snapped the cam girdles in the head because there was that much force. As for the VE, it survived.

Exactly. It's a good picture to bring out to show people what being cheap and not shelling out $60 for oil and $12 for a filter once a year could result in.

Um, the OP said that the cheapo basic oils like Castrol GTX and valvoline XLD have high detergent. Is this true ?
I've always gone by the logic that expensive oils have better / more detergents and therefor do a better job cleaning your engine. Can anyone confirm ?
Back on topic, if your engine is sludged up bad i don't think any number of oil changes is going to fix it. I'd be definitely popping the rocker covers off and scrubbing it if you have the skills to do so. Be carefull and make sure you don't let any chunks fall down the galleries.... plug them with rag before you do anything. A Denstist vacuum would be awesome for this job.

the best oil to use for "cleaning" purposes is a diesel oil, caltex "delo 400" has the highest detergent rating ive come across, castrol GTX diesel is pretty good too
most alloytecs are too far gone to flush out... usually needs the covers and sump off to do the job properly

In my opinion the oils used are adding to the sluge problem because of additives in the oil. I would not use a Valvoline oil even if I got a tanker load for nothing.
Use Castrol Modern engine and change the oil and filter every 6000 k works out about the same as the dearer oil with 10 000 k change but is cleaner for the engine .
I would flush it with 50% Kero and engine oil a few times and put in a new oil filter each time . Drive it slowly around the block each time. Then when the oil filter stays clean . Then new oil and filter and see how she goes for a while and if ok new oil again in a few weeks . Then every 6000 k.
Some service people charge you for top expensive oils but put in crap oil instead . I have seen situations where the oil was not changed at all.
If I am paying for a service I put a nail polish seal on the sump plug although some wise asses just crack the plug and retighten and I sample the oil after . Mostly I do my own .
Also if you get oil into the cooling system after it is fixed run Kero as coolant for a while to absorb and strip the oil , then water to strip the kero then normal coolant .
