How to Install a 1.4 HDi Intake Manifold?

Hi friends, if anyone has replaced this cover before or is an expert in this area, I'd like to get some advice. I mean, is there a special method for getting it to fit perfectly in that part, or is there anything I might have missed? My car was leaking oil from the intake manifold cover, and the PCV valve was faulty. So, I bought a German-made intake manifold and installed it myself. But either I made a mistake somewhere, or the part I bought was too big. I think I didn't seat the 4 oval intake ports at the rear properly, although I did force them quite a bit. Air is leaking from there, and naturally, the car blows black smoke when I accelerate. 1.4 HDi intake manifold example https://ideacdn.net/idea/dl/79/myassets/products/505/0361n4.jpg?revision=1697143329 antipollution2024-03-02 15:29:22

Hello, did you check the part number of the intake manifold with the chassis number? There are two types of manifolds, 6103q5 and 6103n4. One is vertical and the other is oblique. The one you see in your photo is oblique. The o-rings on the back are difficult to install. The technician I had install it had a hard time too. They applied grease or something similar to the o-rings, and even smeared them thoroughly. Did you use any grease-like material when installing them? Other than this part, I didn't see any other difficulties during installation.

There were a few other brands, all for 1,800 TL, and the Febi was 5,000 TL. I bought the Febi, and its exterior looked really good. Then, when the mechanic wanted 10,000 TL, I decided to do it myself. Actually, it wasn't just about the money, but also because I wanted to be more careful and meticulous, as I'd always be able to handle it better with my repairman. I'd always replaced the Octopus fuel hose and fuel filter myself in the past. Anyway, I finished the removal and cleaning of the old silicone residue in about an hour and a half. Then I applied the silicone and replaced the cover. The rear screws wouldn't fit. I figured it was an aftermarket part, but I wouldn't expect it from the German Febi, so I installed two screws with the nuts loose. I installed the top screws perfectly. Naturally, there was an air leak, and the car emitted black smoke due to the rich mixture. Then, it gave an anti-pollution fault, and it wouldn't exceed 3,000 rpm anyway. The next day, I started over. The screws wouldn't fit. I tried the old cover and saw the same thing. So, I called some experts who I knew, thinking there must be a technique involved, but they said you couldn't get it to fit. I asked online forums, but no one could find a solution. Just as I was about to take it to the repairman with a tow truck, I noticed the sharp ends of the screws. I confused them with the others, thinking they were the same ones above. The sharp ends of the screws were inserted diagonally, causing them to pull down the cover as they entered. So, I finally found it :) I've been using it for about a month without any problems. To fix the Antipolito's problem, I disconnected the terminal and waited 5 minutes. It didn't come back. Thank goodness there's no smoke. I hope everyone else is having the same problem.

Hello, first of all, I hope you get well soon, after a certain mileage and age, there is a problem due to the PVC valve on the rocker cover. The original part is expensive, about 10 thousand TL. I also looked at the Febi brand as an aftermarket, but then I looked at domestic products and bought the Zegen brand. The price is 1250 TL as of September 2023, I paid 1000 TL for the labor for the replacement. The rocker cover is difficult to remove and install, but asking 10 thousand for labor is excessive. This part also needs to be removed to intervene in the injectors. I had the injectors cleaned in January 2024, the washers and seals were changed, it was connected to the machine and the settings were made, I paid 5000 TL in total, here 500 TL is for the materials and the rest is for labor, there is also the part for removing and installing the rocker cover.

Really, sir, it's very good. Yes, they mentioned the Zegen brand as well. The partsman quoted between 2,000 and 2,500. I recall. The 10,000 TL labor fee included minor work like cutting the brake vacuum oil, but it really wasn't worth that much. Only 1,000 TL is a really good deal, and it's the right price. I was willing to pay 2,000-3,000. It's not a job that takes a decent person 1.5, at most 2 hours. But I also asked about the injectors. I can remove them, but just the cleaning and cleaning fee is 5,000-6,000, which is what the injector shop would charge. He said he'd need 10,000-15 injectors if the nozzles were changed. Sir, if you could remove the cap, remove the injectors, and then have them cleaned by the injector shop for 4,500 TL, that's great. Which city is it in?
