Hey everyone,
I’ve recently purchased a move and every day I’ve been replacing the olds worn out parts. My next venture is to remove the disgusting amount of sludge within the engine itself. I’ve tried Nulon “Extreme Engine Flush” to no avail. It literally did nothing. Do you guys have any other engine flush suggestions or will I probably have to take it apart and do it by hand?
Thanks in advance.
do it by hand is the best bet so you are sure to get everything out, engine flushes are a gimmick for the uneducated in my book
Yeah, I don’t disagree with you. Just thought I’d give it a shot to try save a few hours of time. Oh well.
I avoided watching the following video, assuming it would be rediculous. But when I did, the engine they were flushing indeed didn’t blow up, as I expected it to do.
The flushed it a couple times, before removing both oil pan and rocker cover, only to find out why the first flush filled the pan with much thicker fluid than had gone in.
Unfortunately, they didn’t show a close-up on the cam lobes and didn’t remove a rod bearing, to see if any excessive wear took place.
If you’ve got an oil burner and have a set of new bearings and camshaft availabe, what would it hurt to perform a similar flush for freeing up any gummed-up piston rings? Feeding some of this fluid into the intake might also free rings, if done systematically:
Here’s a before and after on the camshaft. The view obviously isn’t as accurate as when seen personally up close:
If it didn’t adversely affect the lobes, perhaps the best way to flush an engine would be to do it, without putting a load on it and running it at low enough r.p.m.s to keep the oil pressure light out
To everyone DO NOT use BRAKE FLUID as flusher it clogs up the crank journal oil galleries and will spun a crank bearing.
I dont even use commercial engine flushers last.time engine bearing spun so
I use the old school method we learned at school
I use on the ad-10 engine 30% atf-A and 70% 10w40 sl oil mix
I used ATF-2 mix 50% and normal engine oil 10w30 SL oil
with the ED 10 engines
With ed20 its 50% atf-2 50% 10w40
with EJ 5w30 c3 50% with 50% atf-4
With 1KR 20% atf-4 or higher 80% 0w20 sp c5 oil
I dont take it out just leave it in for minimum of 5000km and then drain repeat the results are awesome
I started with engine oil consumption
With my 1kr
1l:1000km
then after 15000km so 3 changes
1:3000km
After 30000km so 5 changes
1:5000km
After 35000km so 6 changes
1:16000km
Will add this ratio to.keep the engine clean
