I dug a 92 300 out of it's burial site. I literally found it rotting away in a field because the owner gave up trying sell it. There are a ton of problems with it but hearing 2jz and seeing a clutch made my pants fit tighter. Now that it's running well I want to start cleaning it up. The seals are shot and looks to have been that way for a while because the engine bay is covered in gunk. I found in the search that it's a bad idea to go at these things with a pressure washer but I can't find how problems are avoided.

So, what's the safest way to clean the engine bay?

 

Cover up the alternator, engine degreaser, like Gunk/CRC, let it sit for like 10-15mins, then you can pressure wash it, just don't hit the electrical so damn hard like you wanna remove it with the pressure washer and you'd be good. Then you can hand wash it with soap before spraying an engine detailer to make the plastic parts shiny. The cleanliness that you're looking for would all depend on you preference of clean. I've been doing this since I got my SC and I've never encountered any problem.

 

DO NOT pressure wash it.... Kingphil, you're gonna make this dude **** up his car with that type of advice.

2jz's are prone to getting water in the spark plug valley when you pressure wash teh engine bay or even use a normal stream of water from a hose.

 

Thanks for the info

 

A spray bottle and some paper towels. Lol

 

brake cleaner

 

This this this. Play it safe, take your time and do it this way.

 

WD40 Period.
cleans very well.
if you want to make the black parts shiny..
then use silicon spray - also helps as a protectant.

 

I said not to hit any electrical components. I don't know about you guys but I've always washed my engine bay with a pressure washer even with my old cars and I never had any kind of problem.

 

While I would personally play it safe and hand wash it, I have been working at a dealership for 2 years where every cars engine bay is hosed down with nothing covered up and can only recall one vehicle that had a problem.

I still wouldn't do it. But I understand the appeal, after looking at a 20 year old engine bay

 

I'd advise not to pressure wash it.. just spray brake cleaner everywhere, then use whatever else to touch it up.

 

Kinda hard not to hit that area since it's right in the damn center. If you are spraying the entire bay with an APC or some sort of degreaser, one way or another you're gonna need to rinse that off and avoiding the ENGINE is kinda hard, especially with a PW.

 

steam cleaning it would be even better. far different from pressure washing.

 

DO NOT PRESSURE WASH. Even if you do cover up all the electrical stuff. Water will leak somewhere and then later you'll be putting a thread up with help i washed my engine bay now wont start.

This, i WD40 my engine bay.. wel more like 1/10 of it i got tired of scrubbing haha. Made that section of the engine bay REAL nice and clean.

 

I have mixed opinions on this. I have done the pressure washer thing and had some negative results. Done it on another SC and had no negative impact. I would just be real safe and gentle.. Spray it down fast and have a air hose ready to dry it off.. along with leaving the engine running during the whole process. Thats my results and impact!
