Washed mine two weeks ago. I've never had issues with it. Just take your time and avoid spraying to much water on the coils. I also warm it up a bit before washing.

 

To the OP:

In your case, you can get away with washing the engine, because you don't have COP's. Do it on a COLD engine, and when you are done, pull all of the plug wires at both ends (one at a time), blow out all of the plug wells and coil towers with an air compressor, then reapply some dielectric grease when reconnecting them. Use the compressor to blow the rest of the engine dry, especially around all electrical connectors. When done, start the engine, close the hood, and let it warm up to evaporate the rest of the moisture.

 

Thanks for all the great info a pictures guys ! I think I'm going to give it a try on Tuesday Night or early Wednesday morning . I will try to get some before and after pics. and post them.

 

So how big of a deal is it if I don't have compressed air and just wipe things down. Not that I want to use it but I do have leaf blower but I would feel pretty silly using that.

 

The COP motor coils don't seal that well over the plug wells.
If you get water in the wells you will have problems.
They usually don't clear out with heat.
If the boots are old and hard you have even more probability of trouble.
SO wash away and accept any results.

 

Cut up an old towel, shove a piece in each plug chamber. They'll fill easy if you don't.

May cause cranial stress overload, unknow, - from ignition compromise.

Might want to wrap the coil packs as well.

A leaf blower is better than nothing. At least you can knock off the water beads. The longer those exist, betters chances of infiltration.

 

it is so fortunate an unfortunate that I do not have the coil on textile ignition . I have tower style ignition , it's fortunate in this instance only other than that I wish I did have the coil on pack style. I've cleaned many engines prior to this and get going to give this one a go tomorrow.

 

Coil pack= Single coil for multiple cylinders. coil on plug or COP ignition single coil on each plug. I've heard Coil packs called towers before.. I think this is where correct terminology becomes important.. There was a thread awhile ago about this.. Dont confuse yourself and others about what you got You have coil pack ignition..

 

Yep thats what I get for being to lazy to type and relying on my speech to text option on my android phone.

Coil on plug not textile and a few other good ones I will let you find.

 

Its something I leave to a detail shop myself. Always worried about pressure washing an engine myself, but love seeing a clean engine bay, and I drive so much gravel that they probly hate me when I bring it in there. Under the hood and the massive amount of brake dust on the rims are well worth a little OT to pay someone else to do it.

 

I figured you had an issue like that. Allot of confusion comes up with the use of coil pack when referring to COP ignition.. Not trying to make you look bad or anything like that..

 

Here are the coils I have.

those are refered to as coil packs

C.O.P. stands for coil on plug....there's one per cylinder

 

Yes I know I was attempting to say that last night but I was using speech to text software on my phone and it came out very wrong. I guess I refer to these as tower style coil packs myself. Thanks 88

 

I've heard people call them that and I think its very clear they mean coil pack.. The confusion starts with people referring to COP's as coil packs.
