    The Dorman intake manifold was easy to replace. The OEM intake emanifolds are known to melt the opening for the EGR stovepipe and leak coolant from this location. The Dorman product comes with a new replacement stovepipe tube that doesn't make any contact with the intake manifold and is also easily installed. The instructions give you the exact torque specifications and order of tightening the manifold bolts. I reccomend replacing the lower intake gaskets and the Valve cover gaskets while you have everthing else apart. There is simply just more room to do so and it will only cost you an extra $100 to do and is not that difficult do either.

              Comments about Dorman - OE Solutions Plastic:

              Installation was relatively easy. Pull the fuel lines, disconnect all the various electrical plugs, pull the injector manifold, pull the intake bolts, wrestle with the throttle body nuts (two of them are a bit tough to get to)then put the included gasket on the replacement intake, put the rest of the assorted parts together on the intake (watch the plastic internal tube). Be sure to clean the surface where it is going. Don't get gunk in the injector holes. Take the opportunity to inspect and replace or clean the injectors. Put it all back together and torque it based on the instructions. You will need to beg, rent or borrow an INCH/Pound torque wrench. 15 ft/lb is about 85 in/lb, but it's NOT the same! Torque on this is very important, you don't want to break any part of it 'cause cracks will make your car run VERY poorly. All-in-all, well worth the time and money. Only took about an hour and got rid of the intake leak.

                      Made better that the Delphi one I purchased from
                      General Motors seven years ago. I can see from the way it is made with the metal sleeve installed in the EGR passage with space between that this one will last longer. Not an easy install with removing old sleeve but probably well worth the effort. Instruction sheet with it was a help, as the one seven years ago had nothing. Found mounting bolts on the old one were loose after seven years so reinspection will be in order from time to time. Probably should have Loctited bolts though as this was the reason the second one failed.This car has only 72000 miles on it, even though it is a 1999.Seems as though the original design was flawed, and Dorman improved it.My suggestion would be to retorque bolts after a period of time.

                      The shipping time and packaging was excellent. The instructions inthe box were helpful and the overall product was just like oem part. The one thing that was disapointing was that the new lower injector o-rings were not the correct ones. I had to use my old ones as I live out inthe boondocks of Montana and could not afford to take the time to send them back through the mail and wait for the right parts to come. Nor did I want to go to town and buy ones when the ones I thought should fit did not. I would still reccommmend this part and Advance Auto to folks and in fact have.

                        I torqued this item according to the instructions. Numbers 5 and 10 (according to the torque sequence page included with the intake) crushed and split the plastic before reaching 75 inch pounds. All others torqued just fine to 89 inch pounds without any damage at all. Anyone else have this problem or heard of someone else having the same problem?

                        • A:

                          The OEM manifold, or "upper plenum" has an EGR passage which allows some exhaust gases to be recirculated for emission control purposes. Over time, the heat causes the passage to distort, eventually burning or cracking through to the adjacent cooling passage. When this occurs, coolant enters the intake ports, causing at the least white steam from the exhaust, and at worst, catastrophic engine failure due to lost oil pressure. The new aftermarket version has a metal tube that shrouds the EGR passage and prevents the heat damage.
