Good morning, hope it has been a good week so far.
I am going to be dropping the engine on the AZ car (one with the oil blow by) soon and will be finishing repairing all of the prior owner AC line holes with new metal etc. I will also be repairing some minor rust on the batter tray (fortunately then tray “frame” and support are in good shape.
This strikes me as the right time to reapray the engine bay, and was wondering if others have done this and any tips or best practices they have to share.
Obviously same paint color as exterior and same paint family/sourcing as will be used on exterior, but any prep and other tips?
Thanks in advance for the ideas.
It's a thankless and tedious job because of the complicated parts/surfaces. You could spend weeks in there to do it right. Lighter colors are worse than colors like black. Black hides some flaws, white or yellow doesn't.
Good luck.
I just did this. Ended up removing everything and using wire wheels followed by abrasive blaster for the corners. It was miserable.
Hi, I'm in the same process right now... Lots of corners etc to work on. Also lots will be covered by equipment in the engine bay. Because I had to do welding on hell hole and jack points I stripped most of the engine bay.
Hope this helps... I covered the wiring loom / snorkel with plastic and wrap it with tape to keep it out of the way...
PS Battery tray not yet in... And before spaying I will remove the rear window...
Thanks @http://www.914world.com/bbs2/index.php?showuser=23255 , you are doing nice work there!
These are the guys I spoke with, happily it looks like they’re still in business.
I have done this as well.
Go to HF and buy about 3 grinders for the job if you don't already have them.
Get a couple of the cheap electric drills at HF for this as well.
You'll need an assortment of flap disks with various grits and wire wheels, in sizes and shapes. You'll figure out what works best and choose your favorites. Having 3 grinders and 2 drills will save you significant time as you won't have to change them out each time you want a different removal method. Get an extension of some sort for the wire wheels to get into the corners using the drills.There are a lot of them and they are all hard to access. Don't use air tools or battery powered tools as these will slow you down, and just aren't the tool for the job. Add a large access hole on each side of the battery tray support for access. You may consider removing the tray support to clean up the right long, and replace the support with a new one. Dimple die the holes for strength if you have one. Remove everything now for the best job - Make sure you have a good set of gloves, a respirator and eye goggles. If you don't use these your ability to get the job will be drastically impeded by either the dust in your lungs, eyes, or the pain from your bleeding hands. I'll see if I can find a pic -

Wow!
The end result is directly proportionate to the amount of prep work you put into it. I say take your time and remove all components you are able. Use aluminum foil and/or good quality painter's tape to wrap stuff as it is easy to contour to the items and use. Sand and clean the heck out it more times than you believe necessary. Use some air pressure to blow it all out and get all the dust and gunk out of the engine bay. Then go over it with a wax and grease remover several times. Tape tightly and then make sure that you have great lighting so you can see in all the nooks and crannies. Take your time and you will be rewarded with an engine bay that looks like it did when new.
Hi Tom, I’m also in the process of prioritizing the engine bay to prep it so I can install the engine then do other part of the car. Trying to clean most of it and if I can keep original paint like of the engine bay except the firewall may really need some painting after wire brushing those sticky adhesive.
Thanks again for all of the responses.
I talked to that firm this morning and sent them pictures of a 914 engine bay, they’re going to come back to me with a price estimate which I will share with everyone here.
One important update – they require the car be brought to them now rather than doing mobile work, totally understand that from their point of view.
FYI -- if you media blast that BEWARE. Holes in the upper frame by the trunk leading edge lead all the way down into the longitudinals. Likewise holes are in the rear bulkhead that resides in front of the trunk.
Personally when I've media blasted, I find residual sand coming out of everywhere.
If you don't carefully clean out these hiding places, the media will blow out only when you're ready to apply the final coat of paint.
When it's all said and done, be sure to go back and clean out drain holes on suspension console, longs, etc.
I would try to find a teenager that wants to work, set them up with all the tools and protective equipment. Blasting will makes a mess and takes a lot of time to clean up.
Removing the original glue that secured the firewall back-pad is another nasty part of the process.
I can tell you from experience that when my chassis was blasted, it was then purportedly blown out a couple times by the guy doing the work to remove all of the remaining blasting material. I then transported that chassis across the country, 2,500 miles in the back of a truck. You might think anything still remaining would get shook out during that 4 day drive.....nope. When Kent opened up the chassis to repair it we found a lot of blasting material stuck up in the sail panels and elsewhere. I would try anything else before blasting, which would be a method of last resort.
