Hi everyone,

 

Purchased an 05 OBW recently.   The leaking HGs and torn CV boot were repaired, but plenty of oil and grease cooked and caked over parts of the bottom of the engine, AT pan, and filter.

 

Tried the Gunk Heavy Duty Gel.  The can says to protect electrical components, but this video by Gunk says it is safe on electrical:

 

I did not protect the electrical.  Sprayed on a cold engine, waited almost 10 min followed by a thorough rinsing from below, then from the top of the engine to rinse off anything that may have splashed up.

 

It did a fantastic job -- surprised how clean it is.  No problems yesterday or today with the car or electrical system.

 

Hopefully this info helps somebody

Didn't know it was going to post the Youtube link like that.  Sorry, hopefully I didn't break any fourm guidance. Please let me know if that is okay or if I need to remove it.

IMO, I have found that all those engine degreasing products work pretty well. Going to a "wand" type "do it yourself" pay car wash is a big plus. The high pressure water does a much better cleaning job, compared to spraying off with a garden hose.

I've wondered about that, Rooster2.   A concern would be the high water pressure forcing water into places it shouldn't be (around gaskets or onto electrical boards or something?).  Was also concerned about splashing cold water onto a hot engine, but I guess that happens when driving in the rain.  Maybe I'll give it a try sometime...the driveway will be a lot cleaner

I've used similar engine degreasers with good results.

But I never do it on my driveway. I don't want to risk the chemicals eating away at the asphalt.

Don't recommend using the degreaser on your home driveway. It has been my experience that most of the degreasers use keroscene as a major ingredient. You don't want that stuff, and grease and water on your driveway, with a possibility of tracking it in your shoes to your house. Any solvents in the degreaser brew may degrade an asphalt driveway, if you have one. So, prolly good to hose down the driveway pronto after using a degreaser.

 

I think any degreaser isn't good around gaskets, but using on car once every 2 years or so prolly will not cause any problems. If so, the degreaser mfgers. would advise on the can label.

Gunk is good stuff for degreasing.
