Lim gasket 3800.

A factual anecdotal note for fans of the metal framed LIM gaskets whether 3100/3400 or SII 3800. I did a job on a GM car (GA GT) with 3400 V6 engine with the revised GM metal LIM gaskets. The metal portions of the port gasket frames were pitted and corroded. Also, it looked liked electrolysis was taking effect eating away at the aluminum lower ...Anatomy of a Lower Intake Manifold (LIM) gasket fail: causes and symptoms The most common failures of the 3800 engine are spark plugs, wires, MAF...IIRC the list price for the 3100/3400 gasket set is $130 or so from NAPA. I would imagine the 3800 set to be similarly expensive. Order it from NAPA and make sure to request the aluminum-backed one. They probably keep them in stock so it wouldn't be an issue for them to open the package to verify. It's not a Dex-Cool problem, BTW.Manifold Gasket..

Makes sure you install the 2 O-ring seals [at the back] on the LIM, between the LIM and Supercharger. Re-fitted the Supercharger and Gasket, and also torqued the bolts accordingly [and in sequence] Replace the O-Ring on the Tensioner Fitting, [I also applied Gasket Cement on and around the Seal] Re-installed the Tensioner BracketHow do the intake gaskets hold up on the 3800? Is that a weak point like on the 60 degree V6 engines? ... The L26 (04 UIM) will bolt up directly to the L36 LIM, however... the TB will not bolt up. You would need the Gen V to L67 TB adapter to bolt your TB to the L26. And, since the L26 TB neck is longer than the L36, you may need to do some ...

its a pretty straight forward gasket replacement. Drain the coolant. Remove the fuel Rails. remove the Supercharger ( leave the TB on) remove the Lower intake. wipe up any coolant in the block. flush some oil down the valley of the motor. and then reinstall.2) measure pressure with key on, engine running. (should be 40-50 (lower than engine off value) 3) goose throttle and watch pressure. (should maintain pressure, not decrease) 4) disconnect vacuum to fuel regulator, measure pressure. (should immediately increase and hold) 5) reattach vacuum to fuel regulator, shut engine off.

I have the LIM off, the gasket is definetly wasted... totally blown apart as usual right at the coolant ports. But heres the problem with the lifters.... There are 2 (with the motor in it current position) that have 1/4" of free play at the rocker arms!!!. The rockers are unadjustable and are definetly tight.Gaskets & Adhesives. Gauges & Gauge Pods.

The issue of LIM gaskets on the NA SII 3800 engine regardless of GP year '97-'03 is not whether they will go bad or cause issues but just a matter of when. Here are some better resolution pics (800X600) out of my collection on the upper part (UIM) and new LIM gaskets (FelPro).

I am interested in purchasing a 1998 Pontiac Grand Prix GT 3800 with only 84K miles on it. Everything inside and out is pretty much mint. However, there is a definite oil smell when running and when looking under the hood, there is oil (I think it is oil) visible along the entire length of the front/top of the engine.Pan is steel, and looks to be held on by a frame between bolts and the pan itself. Up top, looks like it's also coming from the valley seal for the LIM. Coming from the corner nearest firewall on front side of motor, and making it's way down. Seems straight forward enough, oe LIM gaskets are a well known weak point on the 3800.Do you have the EGR on the car still? If yes, unbolt the tube from the EGR to LIM and look at each end holding it up to light. Move the holding piece around a bit. These thin tubes like to crack.

When the lower intake gaskets get old, the seals around coolant ports begins to seep a bit. And when the engine cools, the oil near these ports gets sucked into the coolant as it cools.Mar 19, 2019. #10. Apparently some are not familiar with the F-body version of the 3800. Intake manifold gaskets still fail, but not as common. The F-body 3800 has an aluminum intake manifold, (no composite upper) therefore disregard anything you hear about the dorman or ATP greyworks manifold, and stove pipes.In addition to the LIM gaskets you also get hit for about about $30 for the set of two ZZP Gorlock gaskets.

When the lower gaskets failed, I saw some leaks around the area where it meets the heads. In addition to that I was losing coolant and would have to top off.

Hand-ported LIM is typically going to run you the same $ for the part, plus say $75-$100 in labor (depending what all you get done to it).2) Find yourself a 50 ohm, 180 ohm, and a 1450 ohm resistor. Connect these resistors one at a time between terminals A and B and look at the dash guage.

Possible causes of leaks in that area are: -Throttle body to UIM (check William's post, the UIM passages degrade and crumble and can cause leaks). -coolant bypass (sits just below the throttle body on the LIM). -leaking out the the LIM gaskets and following a track until it gets out the end between the LIM and block. -Larry.Jun 18, 2013. #5. Yeah and the upper intake was also a sure killer on the earler model series IIs. The later series II supercharged with a rod knock is kind of surprising, but could've been due to the lower gasket. (I don't think the Buick-derived cast rods was a strong suit either, cast rods higher rod/bearing failure rates). That some bad luck.Jun 3, 2011 · 3) Add distilled water (buy bulk from a supermarket) through the thermostat housing until full. 4) suction out from lower rad hose. 5) repeat steps 3-4 until the washings come clear. 6) fill completely with distilled water, connect rad hose and thermostat housing.
