engine cleaning
#1

I've had my 68 for over a year now and the engine is in need of a good cleaning. I've used engine brite in the past on my other vehicles and have had OK results with no issues.



note: When I got the car the engine was incredibly clean; Hoses, belts and that beautiful aluminum cam cover was all shining. I'm looking to bring back that sparkle.



Recommendations? -outside of professional services that is.

my favorite is Steam Premium, if you can find it - goes on a hot engine, hoses off - amazing stuff - probably not environmentally friendly



after that, it's all about the hose and a rag, finishing off with the same products i use on the outside of the car

After I put on the engine degreaser, I wipe averything with a rag before I hose it off. I also use a selection of cheap paint brushes to get in the hard to reach areas.



Also it is best to try and keep any kind of engine cleaner of the fenders and such. Some cleaners remove the wax and leave stains which need to be buffed.

5.00 for the steam premium not bad. No offense but unless this was used on your daily how would you know how well it works?

I use Simple Green household cleaning solvent on a cold engine and rinse off with low pressure water from a garden hose. Then wipe everything down with a rag and polish and preserve as needed. Good luck, Bob Blackwell.

Simple Green HD (Heavy Duty) - it's purple instead of green - for most general purpose stuff. I like the Gunk Foamy Engine Brite in the silver can. Works better than regular Gunk for the tuff stuff. I'll have to check out Steam Premium. Also, use a shop vac on blow to easily get rid of loose stuff, leaves, and crap you pick up from the road.

Nice tip. My cheap little shop vac doesnt reverse but I have a air compressor that should work wonders.

while the compressor will work better for sure, are you sure you can't plug the hose into the other end of the shop vac? or is it an off-brand?

My wife got it for me from Target because it was cute and small enough to be tucked out of the way. There is only one way to attach the nozzle and the filter size is so off that they can only be purchased from target and do to the low amperage the unit is really only good for vacing the carpet. So no, its not a real shop vac. Why do woman even bother buying tool related items for us?



Do I sound bitter?

Thought I would put this in here rather than start a new thread...if I had started a new thread it would called: Weird yellowy film stuff on my cylinder head and intake manifold.



I just started noticing it - they were nice and shiny, now beginning to look gold / yellow (should have taken pictures). Plus I say a "film" but (1) it doesn't wipe off and (2) on the cylinder head it seems to be peeling off in places kind of like a coat of something that is now turning yellow and...peeling off? Bolts are yellowed too...



Has anyone ever run into this? Ideas to clean this up and make a bright shiny silver again? Kind of like the picture of Etnier's posts?

Superclean by Castrol works pretty good and a leafblower works better than a vac for blowing

Sounds like the dreaded cosmoline. As far as I know it is a PITA to remove.

Cosmoline - really? Hmmm...



I found this as far as removal tips:

I'll try something along these lines and see what happens. It seemed like this yellow stuff just appeared over the past few months or so...but I could have been missing it...

any chance that the PO sprayed a clear coating on these parts and that it is starting to flake off and discolor with age/heat?

I was thinking the same thing too...am hoping that some of the Cosmoline removal ideas might take care of it either way - I hope!

I've used this method on all my cars. Works extremely well.

Chris,

I mentioned it because I painted my "valve cover" silver and covered it with clear WURTH paint for protection. The clear turned yellow from the heat. I removed the clear and the paint to get rid of the yellow. No flaking, just discoloration. It took a little less than a year the yellow up.



To get a nice silver finish on the intake manifold I use ACE #16444 chrome, aluminum, heat resistant paint. Apply a light coat with a rag. Comes out very nicely without any brush marks. Also works very well on the cover.
