Chapter 9 Part 9: PT Cruiser Turbo Motor Reassembly - Intake Manifold, Fuel Rail, Throttle Cables

Installing the Lower & Upper Intake Manifolds, the Fuel Rail, and the accelerator and cruise control cables to the throttle body.

Well, good job! However, let me make some comments. Installing an additional oil cooler is not the best solution. Because it is in the supply line from the pump, it is under a pressure of 2-6 bar (when the speed engine is high and it is cold oil). Worm-worm clamps are not able to compensate for temperature fluctuations. And also the fragility of rubber hoses. These hoses can simply be torn out! Very dangerous is the fact that over time and high temperatures the rubber hardens. And small particles from it can clog the holes of the oil nozzles, oil channels of the crankshaft and camshaft.
I work as a heavy equipment mechanic. On excavators, the engine filters are located on a remote base, with hoses. And often the excavator engine breaks down due to a piece of rubber that has peeled off from the inside. My recommendation to customers: as soon as the hoses begin to harden, change them immediately, or remove them altogether, if possible. This is a design feature of CAT, Komatsu and other machines.
My advice: Install an additional oil cooler between the turbocharger drain and the oil pan. Use copper tubes (any suitable metal). Fewer rubber connections. The drain from the turbine does not contain much pressure and goes directly to the oil pan. Where is the mesh fence, oil pump, filter. Good luck!

Thank you for sharing your insight. I appreciate your input and you certainly sound like you have very valuable experience - especially on large/heavy equipment.
2-6 BAR (if I checked the conversion correctly) converts to as much as 90 PSI. The Oil/Transmission cooler hoses I used are rated for 250 PSI. Here are some of the specs of the hose I used:
Working Pressure: 250psi; Burst Pressure: 1000psi; Temperature Range: -40°F to 257°F; Minimum Bend Radius: 85.5mm.
Here's a link to the product on Amazon: www.amazon.com/EVIL-ENERGY-Transmission-Cooler-250PSI/dp/B0BGCGBM78/ref=sr_1_1?crid=2JKA2EZMKQA9X&keywords=VIL%2BENERGY%2B3%2F8%22%2BTransmission%2BOil%2BCooler%2BHose%2B10FT%2B250PSI%2BSAE%2BJ1532&qid=1705941770&s=automotive&sprefix=vil%2Benergy%2B3%2F8%2Btransmission%2Boil%2Bcooler%2Bhose%2B10ft%2B250psi%2Bsae%2Bj1532%2Cautomotive%2C250&sr=1-1&th=1
At this point I have the entire system fabricated so I'll see how it works and keep an eye on it over time. It would be quite a tricky challenge to run copper tubing and fit a cooler between the Turbocharger and the Oil Pan as it would all be on the back of the block and there is not room and you have the heat/exhaust also right in that area. Not saying it is impossible...but probably beyond my skill!
Thanks again for posting and keep up the hard work!

Another great vid. What coolant hose did you go with and what are you sending that in-line coolant temp sensor into?

[@PTBubbles]

@philsowers Do you mean the Radiator hoses and the Heater core hoses?
This was the kit I ordered from ModernPerformance: www.modernperformance.com/product/mpx-silicone-hose-kit-neon-srt4/03-05-neon-srt-4-engine-cooling-system
The temp sensor goes into a coolant temp gauge in my PT. I have numerous gauges now and setup temp sensors on the Oil and transmission fluid as well.

​@@PTBubblesYes that's the one I didn't realize they were in the kit I haven't needed to upgrade my other hoses but might as well go for it. ​ and I think I noticed in one of your other videos where comments were turned off that I saw you had like at least five dash gauges and you mentioned one was water temperature so I guessed that's what I assumed the inline was for. Looking good! Made sure to turn on notifications so I don't miss your next upload, looking forward to it!
